Do the math with me, let’s say you have an average price of $4.00 per appetizer. If your bartenders service 60 tickets a night each, and if your bartenders were able to add on one appetizer to just half of those tickets, you would generate an additional $120.00 per bartender. Let’s assume you had 5 bartenders on for the night – that would add an additional $600 per night to your sales.
