I don’t like it when the server refers to a group of men and women at her table as ‘guys.’ Typically, she’ll say, “Thanks guys!” as she delivers the bill. And I deliberately refer to a female server because I’ve only ever heard women do this.
I don’t like it when I thank the server and he or she replies, “No problem!” I didn’t thank you for a favour. I thanked you the service you provided as part of a business arrangement. If you think it was a favour, I don’t have to tip you, right? Yea, I thought so.
I’m not one of those people who need to have everything just right. Far from it, in fact. But that said, these two things really bug me.
