You ever do this?
I once got a big bar of Dairy Milk for an administrator after she had to stay late to do some work for me (it wasn’t my fault and she knew that, but still). Handing it over was the most excruciatingly awkward interaction two humans have ever had, though, and I’ve been gun-shy ever since.
I’m thinking of getting one of the administrators a wee bottle of JD because we (mostly not me, but the other perpetrator isn’t going to step up) ran them ragged last week but I’m not sure.
