so a few days ago i was shopping for a dress to wear to a wedding with my husband. i had a $200 gift voucher for one of the stores in the mall so we stopped there first. when we entered i wasn’t greeted immediately, which annoyed me. retail is supposed to be about customer service. but i started looking at the formal dress rack when the lady working there greeted my husband and not me! eventually i found a dress that i liked but i needed a size 16 which they didn’t have. so i had to ask the lady if she could look for a size 16 which i really didn’t like. retail employees are supposed to approach you! and then she took the dress and started typing something into her computer. i firmly asked her again to help me look for a size 16 and she just said that she was looking for another size through the system. computers are not accurate!!! i wanted her to physically look. i told her that i would keep looking, and says “ok no problem” and then starts talking to her coworker!!! horrible service. i ended up leaving the store and driving to another mall so i could use the voucher. today i went into the bad store and it was just her manager working. i made a full complaint to the manager and she said that she would handle the situation. i believe i did the right thing but my nephew is disagreeing with me. am i the asshole?
