Get a damn job, take that damn mop.

On the other hand, what if the robber was armed with a mop next time?

Then put him out of his misery cause that's a "stupid criminal". Or, if the shop owner is feeling a bit compassionate, call 9-1-1 for someone to come take him away to the funny farm where everything is sunny and bright; and he can mop the floors all the day long.
