What do you say to a multibillion dollar hotel corporation that charges insane prices for wifi services and then asks their customers to subsidize their employees salaries by leaving tips? ("WFT?" comes to mind.) I believe all guests should leave tips for the maid services, but hotel giants should pay them a decent wage, as well. Hotel behemoth Marriott -- which raked in nearly $13 billion in revenue last year --wants guests to cough up a little more cash to help pay its hotel maids.
