Did you guys know that there is a limit as to how much a rider can tip?!
"Uber confirmed to CNET it does have a limit to safeguard against "fat fingers." You know the problem: You want to tip $10 but accidently type $100 or $1,000. This way, you won't have to go through the pain and hassle of getting your money back.
Uber's tipping limit is "200 percent of the total, up to $100," a company spokesman says. That lets a passenger, say, tip $50 on a $25 fare. "Of course, riders are free to tip additional amounts in cash if they'd like."
