My wife and I went to went to a local pub earlier today for happy hour when pints are $1.50. We sat at the bar and occassionally talked to the bar maid who is very pretty.
Twice she made a drink in a blender and poured the drink for the customer into a tall glass. Each time she poured what was left from the blender into a regular cocktail glass and gave it to us. My wife and I each had four $1.50 pints (eight total), and I requested the tab. She only charged us for six pints and didn't charge us for two. With tax, the bill was around $9.27 instead of $12.36. I gave her a twenty and asked for two back.
I believe in tipping generously and understand the 20% rule of thumb, but did I tip too much? Maybe too little? Does the hot bar maid factor still apply when you are with your wife???
