At the Water Cooler ...

I put a patient on the table for a 30 minute scan. As I am sliding him in the magnet he turns and hands me a 2$ bill and says "This is to make sure you do your job right!". And then he pulls out literally about 100 business cards all printed with jokes and says "I probably should give these to you to read while your doing nothing." I just smiled, gave him the call bell, and told him not to move. I hate people. Especially ones that think they are funny and are not. Am I in the wrong profession?
