The only way to get by in working in retail is to have a good time. I try to be nice to every customer I get but some customers are just assholes!!
Although I have noticed when you are nice to certain customers they are nice back. I just don't understand why people are assholes when they are trying to get something accomplished. Especially when they are trying to find something and being rude to me then I won't even bother trying to help them find it and just say "we don't have it anymore"
