Mike Mennonno reports he's now gone to Mr. Crepe in Davis Square enough to conclude that it is staffed entirely by grumpy people:

... [N]o human kindness escapes any of them. At least not towards me. And they have trained me not to attempt to show any myself by answering my innocent smiles with glares, or by returning my "good morning" with a brittle "can I take your order?" ...

Plus, they shed eyelashes on the crepes.
