Another thing that you can mention... talk about seat positions, seat numbers.
I can't tell you how many times I registered for a live tournament, the cashier
tells me I'm in the 1 seat and I sit down in the 9 seat instead... instantly, the entire table that is already sitting down knows I'm a total noob. LOL Don't be me!!! Know the seat numbers before you get to the casino, they are always the same, #1 seat is to the immediate left of the dealer and it goes clockwise around to the #9 seat sitting to the immediate right of the dealer. Another good solution is to walk up to the table, slide your receipt to the dealer and just ask the dealer what seat is yours. That won't alert anyone that you are a rookie, it's normal to do that. Also, be aware, it is always the dealer's responsibility to check your receipt when you arrive at their table, so this process should happen automatically. The dealer must check that you are at the right table and actually paid for an entry into the tournament. This is one of their jobs.
Also you could discuss the problem of finding your table, if it is a large casino and a large-field tournament, it can be a terribly frustrating chore to find your correct table. First of all, explain where table numbers can be found, most
casinos use the same method of a small "plaque" or sign on the table where the dealer sits. Also explain that there's a much easier way, which is to locate a casino employee for seating help who will walk you directly to your correct table. Explain that casinos call these employees a "brush" (which is an odd term that nobody would normally know if it isn't explained to them). Also explain to them that there will be a person (almost always in a very sharp suit-and-tie hehe) that is called the "Tournament Director" and he is the one in charge of everything, including all the brushes. The "TD" is also the person who will resolve all disputes at the tables, should they occur. Dealers call the TD's to the table, the players don't do that. If you have a problem with something that has occurred in a hand, immediately alert the dealer who should resolve it. If you're still not satisfied, ask the dealer to call the TD over to the table. Explain the process of this, which hopefully won't happen on our first day, but it if does, we should be prepared for it and know how to handle it.
