It's Friday afternoon, so naturally I am procrastinating at work. I was adding up costs for our wedding and I noticed that our venue paperwork mentioned an additional 6% PA tax as well as a 21% service charge. We knew this verbiage was in the contract, but it just now occurred to me that the wording says "service charge" rather than "gratuity." This may be a dumb question, but is the service charge the same thing as gratuity?
