Quoted from 85vett:

Amen.
I've had people say stuff to me at the local arcade and even recently give me the "look" in a tournament for trying to wiggle balls out of the outlane or doing a slide save to save a SDTL ball without getting a tilt. If the game has a tilt bob installed and you aren't tilting it's hard for me to consider it abuse of a game.

Quoted from Colsond3:

sliding them across the floor, carving their initials into the side, and being overly abusive.

Quoted from Colsond3:

On a crappy condition players game, nothing. If that’s your thing.
Flipper buttons are there for a reason, and games wouldn’t have a tilt bob if they were meant to be slid 3 feet across the floor. When you tilt a game, that means you did something outside of how it is supposed to be played. It isn’t a prize, it’s a penalty.
If you like sliding games, go play a bingo or a flipperless machine.
