Eat out all the time , ask everyplace you go , your may need to compete with the commercial places paying now , .50 - .65 cent per gal , tell them you match what there getting , I tell them to keep the tub out back , in case you have issues with what ever , then see if they will just put used back in the carboys containers that it came in , or leave your own drum , ask what they would like , do not make it more work for them , unless they just like you to take it .
