I agree 100% with Marty.
Here is my 2 cents on this...
These are stores... a business. There is NO EXCUSE for needing assistance in CLEANING up a store or tanks, etc.
Now if a place was doing a remodel and could use a hand building racks, or moving tanks, etc. to get it done very quickly... maybe.
But, I work too much and have a family life at home. I cant volunteer my time to a store because they are too lazy or cheap to keep things clean.
I am sorry if this sounds harsh, but thats how I feel on the subject.
