The fact that bad service from these servers upsets you, helps prove that these jobs are important not "unimportant".I agree that I dislike the roomservice %'s, but I also dislike not having a salaried front desk clerk or manager not upgrade me when I am suppose to be. There are jobs that depend on tipping or these jobs either disappear or the establishment will raise their prices. That's a fact whether you like it or not. As long as any of us see these people as not "experienced" and "unskilled" I suppose we have a problem with letting go with a few dollars.The alternative is simple:cafeterias.But then again, some of them have unskilled unexperienced laborers that refill your glass and take up your plates as you get up for your next helping. Wouldn't want to leave them a buck.Certainly wouldn't want to "subsidise" them.
