Real Hotel
It may feel mean-spirited to go to a developing country and try to scam traders. However, we have shady life hacks for every situation on this list. One Redditor suggested using the name of a real budget hotel when haggling at markets. Anybody who is ordering a fancy rug or antique may save some money.

It doesn’t matter if this sale could buy the trader’s children their schoolbooks. After all, it means a couple more daiquiris by the pool. Now we’re making ourselves feel bad which is saying something. But the counterargument is that they’re trying to rip tourists off so it’s right to scam them out of principle (via Joe1972).
