Wait job

A wait job is where you have to wait on someone but they are late for an agreed upon time. If they fail to meet said time, they are obliged to perform oral sex. Hence the "wait"-job.

You are going on a date and they ask you to pick them up at 6:30 pm. However, they are not ready at 6:30 pm and make you wait for 15 minutes.
They are required to provide you with oral sex for the wait job until completion.
