I have a couple of tap handles that my local bartender gave me. He took me to the bar's office, where there were about a dozen. He said they were left by the distributors. Most distributors are good about taking them back, but every now and them, they just leave them and say, "keep them." Maybe they have lost the brewery as a client? Who knows? But I wouldn't assume theft by a customer or bartender, I would look first at the distributor....including the distributor's employees, who may not be the swiftest sails in the water.
