I never visited "bars" much until I was in the Air Force and then I went to the NCO Club often. You don't "touch" the waitresses there, they could be your CO's daughter or a fellow Airman's wife - in either case "touching" is "trouble".
After I was discharged I came home and, awhile later, got married. After our 2nd child money was tight - so my wife went to work as a Cocktail Waitress. She would work at 3 different bars over the next few years and after the second 'incident' she didn't work as a Cocktail Waitress anymore. Those who are, or have been, Cocktail Waitresses pretty much know exactly what I'm referring to. One GOOD reason to not 'fondle' or 'ass-grab' your Cocktail Waitress is -- there HUSBAND could be in the bar. In which case their WILL be trouble. I don't need to elaborate on what I observed, suffice it to say if it were not for the 'bouncer' and the bar tender some asshole would have been missing body parts.
Morral to the story is -- treat your Cocktail Waitress like you would have other men treat your wife / girlfriend. If that doesn't work just picture their husband / boyfriend is in the bar and, you never know, he may be 'armed'. Still think 'gropping' or 'ass-grabbing' her is a good idea? Good - I'm glad you have found religion and saw the light!
Also, many people do not realize that in many states waitresses don't get paid 'minimum wage' - they make MUCH less per hour than the minimum wage. When the wage in our state was $5.50 / hr I think my wife was paid $2.50 /hr. It is EXPECTED they will make up the difference in tips.If you had a job in which you don't get Health Insurance and DEPEND on Tips for most of your WAGES for the night -- you would have a whole different perspective on how much of a tip to leave. I gaurantee if you were on the receiving end the tip would be much larger.
Now for all you guys out there - here is an 'exercise'. Get a waitress tray and a 12 pack of Bud Long Necks. Open all of them and put all of them on the tray. Now pick the tray up and carry it shoulder height off to your side - lifting it and bringing it down to waist level several times in a 10 minute 'session' while walking through a crowd.Now put the tray down for 5 minutes -- and then do it all again. Tell your Cocktail Waitress what your arm felt like after 1 hour. I'm betting MOST men cannot do this. But you'll leave $1 for a 'tip' - you big spender you!
