We had the whole smoker issue for years.
We had a guy about 15 years ago bring in a Dr's note saying he was diagnosed with Diabetes and he would require a 10 minute break every hour. We had no clue what to do with that one. How do you ignore a Dr's note, even if you are almost positive it's fake? Thankfully he was a terrible worker and was always late coming in, late back from lunch so it didn't take long to address all those issues on their own and let him go.
On a smaller and just anoying scale we had a guy that would never bring lunch and when we ordered in would always decline but would then sit at the table when we all ate and would take food off of our plates?!?! It was so crazy none of us knew how to address the issue... lol
Had something kinda similar. Years ago I worked in a small office and on Fridays we would chip in and buy some beer and snacks for the afternoon.
One guy never NEVER would chip in or buy anything but would always stay and have a few of our beverages; however, he would leave to cash his check and buy a 12 pack but left it in his truck.
On one Friday I snuck out and stole the beer from his truck and told everyone I picked up some beer while I was out. When it was done I thanked him for finally buying! His face went pale!
this guy just didn't get it, and we finally started putting the beer in the Coke vending machine so he would have to pay!
