As you can imagine, the mats behind the bar can get pretty dirty.
Sometimes Dave takes them to the car wash and hoses them down. When it rains, he sometimes uses a much more basic solution: putting them outside by the curb and letting the rain wash them.
One time, it was raining so hard that the mats started to wash away down the street. Good thing the bartenders were paying attention and rescued the mats before they disappeared.
