If you play
Standing in line to register
Getting into a tournament means queuing at the desk in person, often right up to the first hand.
The list only exists in the building
To find out you're ninth for NLH $1/$3, you drive over and read the board.
Your history resets at every room
A new room starts you from zero: new sign-up, new card, no record of where you've played.
Sessions on paper or a spreadsheet
Buy-ins, cash-outs and hours go in a notes app, if you remember to write them down.
