I was shopping at a local Walmart. In the electronics section, and of course blocking the aisle so no customer could avoid talking to them. An AT&T employee started his sales pitch. I told him "no thanks, man. I'm not interested". This angered him, and he started making VERY LOUD and VERY DIS-RESPECTFUL comments. I was told "oh, you don't have time to talk to me? You don't look like someone who would have anything else to do", and, "look at you! I don't even see a phone on you. Can you even afford one?". My phone was in my pocket. Apparently, he thinks there must be some requirement to wear it clipped on a belt or pocket. Anyway, this was not just extremely insulting. It was embarrassing. Several customers heard this and were staring at me. One employee of Walmart looked like he was getting ready to approach him. But I walked away rather than feed into his obvious arrogance. A Manager of Walmart was notified. So he may be reaching out.
