"you could talk to service workers if you wanted to, you just think you're better than them"

As a service worker, don't talk to me any more than you have to

(edit): Felt the need to elaborate on this. It's not that I resent having to talk to you or anything, it's that we're human too and we're prone to the same anxieties our customers are. Some of us are social butterflies, but for me it gets exhausting after a while, so it's annoying when people talk to me about things that aren't related to how I can help them. It's hard enough for me to converse with people I'm actually friends with!

There's nothing you can throw at me that I won't be able to help you with, so don't be scared to come to me. But unless you're telling me you like my hair or my outfit or something, I'd rather jump straight into helping you with what you need.
