Why do the general public who go into retail tend to disrespect employees?

Anonymous
where I typically work, customers seem to be rude often and not appreciative of what we do for them. that being said.. today I had a lady asking for tape, when I showed her where it was she then turns around saying she couldn't trust me cause she was looking for glue. I wonder if she was bipolar...

also at our job, we have months of computer training and have to sign or try to get credit card applications. I can be working till 11pm at night and be assigned to come in at 9 am the next morning and some customers don't understand the sacrifices we make to be there to help them! they never apologize for being rude and seem to never say thank you. What have you done lately to appreciate a retail associate (a human being, stranger, person with feelings) in your life so far? What makes them any different from you? they are people too, I do not understand why rude people are allowed to act like this, it's as if their parents never taught them manners or class. So what's your take? what have you done lately to be kind to a helpful employee?

I'm in general sick of the rude answers on here. obviously some of you, your parents were rude and lacked the time and courtesy to teach you manners
