ELI5: In movie scenes of gambling and betting, people throw up tons of cash for bets - how do they keep track?

People just yell out their bets with a fistful of cash and the bookie just grabs it - is someone taking notes on what they bet on, how much they gambled, and gave them a receipt? Does this happen in real life? It seems so complicated.

They don't keep track because it's a just movie and those aren't real bets. 

In real life you walk up to the betting counter after waiting your turn in line, place your wager, it's entered into the system through a computer and you are given a receipt.
