One day at lunch saw what I figure the employer pay the bill and tip and as the boss walked away from the table, the employee a few seconds behind quickly grabbed the tip and stuff it in his pocket as he walked away from the table.
That doesn’t surprise me. The guy probably lies to the boss all the time, and will eventually get sacked for it.
I’ve had that happen a few times. Once it was the guys brother in law (I knew the main man, as he was a regular, and explained he had family visiting). It was a huge group of 15+ people that ook a long time to set up and break down, and left a huge mess. The BIL waited until the rest of the family left out the doors, and then he took the tip that the regular guy had left me. I was pretty hot about it. More than one incident like that in my time, too.
