Like honestly? Who enforces this rule? The kid you pay $8/hr? Has this rule EVER been enforced?
And how do you clean up spilled gasoline? Like can you just scuff it with your boot a little, spread it around? Do they have a special gas mop? A special sink to clean the gas mop required by the local health department?
And Really? Was the spilling SO excessive that they were like, "f$ck this, we have to put up a sign. We are burning through our gas mops."
