I manage a new and used furniture store and the other day I took a little cat nap in the office. Whoops. I know that's super unprofessional, but it was a painfully slow day and it was the first one that I've done in a very very long time. 

My office manager apparently walked in with photo of a table on her phone and shook me awake to get a confirmation on a price for a customer. I apparently said $300 and went right back to sleep.  I wake up like five minutes later, continue helping at the same customer, and looked at their invoice on the computer. I noticed a table on it and asked her "Amanda, what the hell is that?" She said "It's the table." 
"What table??"
"The one I asked you about in the office while you were sleeping...?"
I had no idea what the hell she was talking about and saw the table that she apparently showed me. The table was a handcrafted all Oak and mahogany dining table and is going for $1,000. At that point I just had to admit and explain to the customer that I have no recollection of her asking me about this table and give him the actual price it was going for. He starts going off saying "no, that's bullshit... that's what I was told and agreed-upon... so now you have to eat it and give it to me for that much." 

I explained to him that I can't give it for that little  and I'll be willing to compromise for this misunderstanding and give him a 20% discount as a floor model and give it to him for $800 instead. He didn't even speak to me directly and starts claiming me as a "snake" because that's not what he heard and I'm going back on my word as a business owner and "a man". I told him that I could easily say that he's a snake back for trying to take advantage of me while I was asleep.

This goes on back and forth for like a good 40 minutes and, mind you, we haven't run a single card and we haven't touched a dime of his. But to him, we already owe him this table for not a penny more than $300. No takesy backsies. It finally escalates to me just ignoring the issue with the table all together and asking them what color does he want the other items he ordered in. He said he doesn't want to buy anything at all anymore. So I said "Great we're done here then" and just deleted the invoice altogether. Now the dude asked me if I want to talk to him outside. 

I said "What we got to talk about? I've been taking to you for past 45 minutes." 
"No, c'mon, I just want to talk to you."
"Why we gotta go outside for that?" 
"I can talk to you behind that counter if you want." 
"Really, with all these cameras are around us?" 
"Yeah I don't care." 
"Yeah man, I don't want to talk to you man." 
"Yeah, I bet you don't...." And he walks out and waits there by his car for me to get out. 

But it's a good thing he did though. The second I saw that door close, I called 911. I let them know that a customer threatened to assault me because of a misunderstanding over a price. About 10 minutes later while the guy was still outside, three cops showed up and started questioning him. They came in and questioned me, I told him what went down, and they told me if the guy comes back, I can call them up and they'll take him away. They're right down the street. He eventually left after he saw the cops weren't leaving. We locked up and I was walking to my car to get home safely

I told this to a few members of my family and friends and they told me one of two things: 
° "This wouldn't have happened if you weren't sleeping on the job like a bum. Clearly, he was way more wrong, but you weren't right."
° "Next time you get a situation, or deal with a person like that, just give him what he wants and get him the fuck out of your face."

I take full responsibility for sleeping on the job. It's just wild to me that the day ended up so "Murphy's Law". It's the first nap I've taken in maybe 10 months and the one person it would have fuck me over with just happened to be the one I got.  But I got it disagree with giving him what he wanted. To me, that validates his behavior and lets him know that he can pretty much do that whenever he wants in my shop again. Or others for that matter. And not just for him, but maybe for his buddies too.

Sorry this post went on longer than expected, but what's your guys take on it? Am I the asshole for not living up to those two bullet points?
