Past the tipping point? Never

It seems everyone has their hand out [“Right at the Tipping Point,” Las Vegas, July 1]. Don’t get me wrong; I do tip. I tip the parking attendant at restaurants, the bellhop, hotel doorman, hotel maid, room service, hotel concierge, dealers, cocktail waitress, taxi driver and the following: Starbucks barista, Baskin-Robbins dipper, bartenders, waiter/waitress, and, more recently, Chinese fast food takeout and, more important, my sommelier.

Can I go home now? My arm is tired.
