Provided you are not at a casino where a rake is being paid for such services, it is clearly rude to assume that someone else should be servicing you by counting the pot for you. Your players have the right to be a bit annoyed at the offending lazy player. The onus is always on the betting player to know and/or determine the pot size. The table should check/confirm the amount is correct. Rounding the pot to the nearest dollar is a must. That said, at many home games you will likely have a player or playing-dealer that generally knows what's in the pot at all times. When I'm dealing/playing, I generally know the count and will tell players when they bet the pot. That said, a polite "thank you", fetching a drink, or tossing a chip to show appreciation if always a nice gesture. I've been at a meetup or two where some players are fairly rude and treat me like they would treat a paid dealer (i.e., not paying attention, not pushing bets into the pot when prompted, not making efforts to speed the game). I generally stop providing a count, stop organizing/pre-splitting the pot, stop dealing, and fairly quickly change tables. Problem solved....
