I'm glad you think alike, milmore104. Some things should be rewarded, but I don't necessarily feel that tipping is necessary for getting your bags to your room or even for housekeeping to clean your room. I do hope they are compensated fairly for what they do, because I don't think it is an easy task.
I just feel sorry for those who pull up to the Disney resort with a car full of kids and luggage. We've all seen them before...they have tons and tons of bags and gear. They HAVE to use the services of a bellman, and with all of their gear, at the customary $1/bag or whatever the rule of thumb is, it must cost them a fortune just to get it to their room. Not really fair to them, seeing as they just don't really have much of a choice.
People should really just be doing their jobs, like you said, and getting paid for that. After all, I am in a service role at a large company, and I don't get tips for doing my job. People should want to be helpful and they should understand they are in a service role, and being friendly and helpful should be a prerequisite for the job, not something we need to ensure that we, the customer, receive by tipping.
