One question

Hi! I have a question about this phrase : “waiting tables”.
What does is mean?

As it is Saturday, I am in a good mood, normally I would encourage you to look it up on Google. (Your own efforts are worth more than anything we can do for you):

“waiting tables” means that somebody is a waiter or waitress - a service person - in a bar, cafe, restaurant etc, etc.

Good luck with your English!

Edited (I had made a mistake in the sentence in brackets).

Thank you for your attention! Actually I have some true thoughts about meaning of that phrase but I want to be sure.
Have a good weekend!
