I have noticed recently when out with a male friend waiters (in several establishments) ask "What can I get you guys".
We are both in our 80s and it seems comical to be classed as Guys. When with a female friend it's usually Ladies, which is fine. What's wrong with just asking "what can I get you" with a smile?
Oh dear, now I sound like a grumpy old woman!
What was your happiest moment today?
