Linkbait title. How do you go from "I tipped someone very well and they did me a favor" to "This will work every single time for any person"?

Want to know a trick to get favors like this without bribes? Be nice to the people serving you! Whether it's someone at a hotel front desk, at the customer service call center, or a bartender... They get treated like crap all day, so when you act nice to them and make their jobs more enjoyable, they'll be much more likely to bend the rules in your favor (if you ask).
