They have this idea they could be rude to retail workers because we work in retail and surprisingly we retail are paid to be rude at. I would like to point out to these people we are not paid to take any ruddiness from customers and we have the right not to serve you if you are rude to us!
Basically just because I work in retail it does not mean I can be treated like scum by frankly people who largely are no better than myself and in the large majority, in my case, are more poorly educated and have less experience with computers than myself!
All it shows lack of general respect people have for each other in this modern world of ours!!!
