Across the board, hotel concierges receive the least gratuity, with just 17% of global travelers leaving a tip; 37% of travelers show their courtesy to the hotel maid and bellhop service, while room service delivery gets tips from 35% of guests.
Of course, Americans aren't the absolute worst. A full 23% of global travelers admitted they don't tip anyone at all. Stingy bastards. France, which tips 59% of the time, and Australia, at 50%, came out looking particularly cheap, but New Zealand wins (or perhaps loses) at leaving the fewest tips, with just 42% of Kiwis tipping whilst on vacation.
As Expedia's Vice President and General Manager John Morrey said, the incentive behind the study was to reveal “how cultural forces impact how consumers save and spend money in regards to travel".
If that's the case, then when it comes to tipping, the US -- a country fond of reminding tourists just how much to tip for the periodic check-ins and water refills -- surely abides by a double standard.
Well now, here's a tip for Americans on vacation this Summer: Tip more! Then, and only then, can you expect more.
