I travel lightly and a lot, mostly for work, living between several countries, so I made it a habit not to accumulate stuff, only passports :)) I almost never carry cash around, and my cards are mostly virtual which is safer and also more convenient. Paying well for service, I expect it to be good in return. I’m a firm believer in people doing their jobs well, be it a nail artist, barista, massage therapist or Pilates instructor. Here’s a simple example: I love white clothes, like really stark white, and I hate it when I get them from laundry and they’re suddenly greyish, and then they tell me “yeah what did you expect, things don’t stay white forever”.
So I got my crisp white shirts back from the laundry yesterday and they were so white it almost hurt to look at, and that plastic bag they came in had an iTips QR code on it. Super simple, pointed the phone camera at it, got the tipping/feedback page, sent a tip to these nice people. That’s how it should be: everyone proud of what they’re doing, no matter if they make apps or launder shirts. The iTips service was a cherry on top for me, all nice and clean and working like you expect it to. Perfect aftertaste!
