I work in a supermarket, last two hours we ahd nothing to do... lol...

We (3 guys) were waiting for empty glass bottles to come in
Normally 1 person can take both of the machines when they are in use, but we were just waiting for someone to use 1 machine and collect 5-15 bottles and then sit back and wait for ~10 minutes till someone puts some bottles in one of the machines again.
