Smiling all the time
I work at customer service and I smile easily. I always smile when talking to customers or if I just have a cause to do it.
When I'm not doing anything and just stand there, naturally I don't smile. This causes one of my co-workers to come up to me and say, "You need to smile!" It really irritates me because he does it EVERY single time we work together. It's as if he expects me to smile when there are no customers and I'm not talking to anyone.
Is it common/normal for people to expect you to do that? I understand smiling if there's a customer I'm talking to, but expecting me to smile while doing nothing seems downright ridiculous.
