Players need to be considerate of one another. Some want lightning fast games, others need more time, either to decide what to play, or in some cases, for physical or computer reasons. Often a player will complain of slow play when there isn't any, the player is just not playing at the speed they want. Other times there is real slow play and the TD's try to stay on top of that. One way everyone would be happier is if you don't enter a tourney if you know you are going to need a brb for whatever reason. Another thing that really irks players is the chronically late player. If you enter a tourney, PLEASE be there at start time. Timers are irritating to the players and the TD's as well.
If you know someone always plays slower than you like to play, don't enter the tourney if it is going to irritate you.... A little consideration for your fellow players goes a long way toward making everyone happier.
