Not an Accident

Working in a bowling alley is supposed to be a fun experience. Your job isn’t too challenging, as long as you follow a simple list of rules. Such rules include wiping the counter before clocking out, counting the bowling balls to make sure they’re all there, and not dropping a bowling ball on the foot of an annoying customer.

The new girl didn’t get a chance to do the first two because she failed the third rule. While dealing with a complaining customer, she dropped a heavy bowling ball on their foot. The OP didn’t elaborate on whether this was an accident, but the girl was immediately kicked out of the bowling alley.
