**Over-pours:**

Analysts estimate that bartenders over-pour by 20% or more. I’ve been more conservative and calculated a 10% over-pour rate. Also assumed is that each bomb has $0.83 liquor and $0.39 of energy drink. If you use two glasses per bomb, over-pours only occur with energy drink because your one-ounce shot glasses provide good portion control.

**Glassware:**

It is assumed that one glass is broken for every 65 bombs served. This number goes up to 1.5 glasses if you don’t pre-mix.

For every 500 bombs sold, it is estimated that 10 glasses are stolen.

Washing 500 glasses (and perhaps another 500 shot glasses) costs $1 in soap and $1 in sanitizer. Filling your sinks with hot water several times (20 - 30 gallons) costs you about $5.
