How annoying are "assistant dealers"?

[iron81]

This is a habit of mine. I like to keep the game moving and I have a little sympathy for how hard dealers work. Here's a few things I do:

- Call hands at showdown, especially in Omaha
- Remind people to put their blinds or antes out
- Push in other people's bets if the dealer is having a hard time reaching (I try to show my hands to prove I'm not stealing from the pot)
- Tell people its their action if it looks like they didn't notice, although I imagine sometimes they're just thinking. I'll look at them and say "action" or do a "palm up point" like a dealer would.
- Feed $1 chips into the pot so the dealer doesn't have to make change to take the rake.

I try to be gentle about it, usually a barely audible "blinds" or "action", but I can see how this might get on people's nerves. I don't recall anyone ever giving me crap about it, but how bad is this?
