Those mugs belong to the mug club. For an annual fee the members buy a mug. The mug hangs above the bar and only the person who owns it gets to use their mug. Each mug is numbered on the bottom of the mug. In return for an annual fee, we offer the mug club members some benefits. On certain days of the week a full mug of beer only costs $2, and on non-mug club days they get roughly 21 ounces of beer for the same price as a 16 ounce pint. We also offer discounts on food and merch, go on the occasional field trip and play in the Mug Club Olympics.
