It's the difference between mixed drinks and cocktails (not that I care what I mix the vodka with), and my point was that I don't tend to attract more tip money from the female patrons when my face is covered in zit-like welts.
The difference between a mixed drink and a cocktail is that a mixed drink has usually two bases (one alcohol, one not), while a cocktail has three bases (two alcohol, usually only one non-alcoholic). That is the difference in price. You are paying for alcohol, not the non-alcoholic ingredient. If you are basing your decision of full face mask or not on the ingredients of a screwdriver versus the ingredients of a cosmopolitan, then I would suggest you overlook your stance on appropriate airsoft safety equipment.
