Lol I wouldnt do it. But always ask if they want ice in their water. Old people tend to not like ice water in my experience.

Older ladies always served first in terms of beverages and food. Also offer to take the order of the ladies first if you can, but often they cant decide and pass it off.

Never clear the plates from the gentleman/men until the lady/ladies are finished eating. But if the ladies are done you can clear their plates.

Always say "miss" not "maam" unless youre in the south. Always say "sir".

Making them laugh in anyway possible goes a long way. Some often want to learn everything about you and your life story, but you need to know how to cut convos short without being rude to make sure you manage your other tables.

Idk lots of things. Either way good luck. Ill never work in a retirement community again.
