I'll be sure to write a bad review about my shitty experience at Sumatra if any of the servers there tries to sell me on a drink, appetizer, dessert, or anything else that I don't think I need, and you damn well better believe I'm going to leave without paying if my server wants me to pay a few bucks for service. Then I'm going to praise McDonalds where I can get shit for much cheaper, and they won't charge me for service. Clearly, they are the superior restaurant.
