Speaking of dropping the oil filter.
One day while changing the oil for a customer, the kind of guy that likes to have his chin on your shoulder while you work,
I asked that he step back while I spin the filter off, well he didn't, my hand became wet and slippery with oil and lost hold of it.
The filter fell to the floor and splattered oil all over his new Tony Lama's, So I take my rag and try to wipe the oil off. Didn't work out very well being they were soft leather boots, he he he. The guy never came back
