Here is another tip for restaurant auctions - make sure you know whether equipment runs on natural gas or propane. Your propane flat grills, fryers, etc will fetch higher bids from your concessionairres and rural restaurants. From experience, it is a royal pain in the rumpus to find someone to affordably change out the orafices from gas to propane.
Something else that is helpfull is to say the name brand of the item before you start auctioning it. For example, my hubby is in a wheelchair and often, cant manuever it throughout the building or estate, but if given the proper info when the item comes up, will know better what he is bidding on and go higher just because of the name. (dont tell him I said that, he thinks he is a cheapskate
