Me and my friends were sitting at lunch, and one of them dropped a quarter and it rolled to my feet. She says "can you get me my quarter?"

We all tease and intentionally bug one another, and I noticed she didn't say please, so I decided to stare at her with a mockingly dumbfounded look. 

She turned sour pretty quick and continued with "grab me my motherfucking quarter" or something along those lines. She sounded pretty serious, but she ALWAYS does, and she does joke around a lot aswell. So I just laugh and say "can you say please?" And some people at the table jokingly back me up with things like, "stand your ground!"

She adamantly refuses to say please, so I kick the quarter a bit farther back, just to bug her a little more. Then everyone at the table seems to turn on me and call me an asshole until someone else grabs the quarter.

I thought it was a joke, but looking back everyone seemed genuinely annoyed with me. I tried to brush it off but it's been eating away at me, and I just need to know, AITA?

(this isn't as deep or asshole-y as other things i've seen on this sub, i just really wanna know)
