Upper East Side delivery guys on guard! The Daily News has a report of a clever, if disturbing, scheme that one crook has been pulling for the past week:

Three deliverymen have been ripped off in three days by the robber, who has used the same scam each time, police said.

He orders food, tells the restaurant he needs change for a $100 bill, then waits for the deliveryman to arrive at a vacant apartment.

When the order comes, the thief puts a knife to the deliveryman's throat and ties him up so he can make off with the food, money and bicycle, cops said.

With job risks like this, not to mention being run over by sandle-controlled SUVs, is it a wonder that some delivery guys peeing in hallways?
