There are also some places that might just do a nice, if not grandiose, gesture for someone on their birthday.

Previous place I worked it was pretty routine for a manager to grab one of those containers of store made cupcakes if it was someone’s birthday and they knew they didn’t mind, make sure they got one and leave the rest in the break room.
Never anything more or less than just a nice gesture.

I’m guessing someone tried a nice gesture and it came out looking sad, so they posed for a picture for a chuckle and moved in. I don’t know anyone who would be really upset by being given a pizza bagel on their birthday.
