[Don Fernando]

Warren, I took pride in my work, but as I explained in several posts here, lipstick can always slip through, it happens. It doesn't mean that the bartender or waitress is a dirtbag who doesn't take pride in his work. Lipstick is the most nasty stuff for a bartender.

And again, nobody's perfect, you make mistakes and so can a bartender. Return the glass, you'll get a new one in a clean glass, no harm done. Stop whining about it.
