I work at Best Buy, and I always provide the best customer service possible. There has been the odd time where there's only been me and one other person working in our department, and it's been fairly busy. Yeah, I've also had the odd customer that just walks out of the store, unhappy possibly, even though I acknowledge them when I'm in the middle of helping a customer by letting them know I'll be right with them when I'm done with my customer.
What I find even funnier is when customers get mad at me because we don't have a certain product in stock. Yeah, let me pull one out of my ass.
Okay, I don't say that right to them....LOL. Still, what do you expect us to do about something we have no control over?
