I use a lot of food delivery apps and do not keep up with the different rationales they use to state one price for a meal, while my total is almost double the price. I don't care if the service fee is a tip or is not a tip, if the app automatically adds a tip as a separate line item, if the service fee and delivery fee is functioning as a tip or not, or if the app service is adequately paying their couriers at all. And that's just in San Francisco! I've done this in many cities and countries where I can totally unsubscribe from tipping culture and not have to even think about the debate because people are not operating under a parallel serfdom regime for wages. I think many "affluent people" have similar multicultural experiences and would just rather not be burdened with the mental exercise. I just have no idea what the apps are doing, I've read enough headlines to assume they're bilking their gig-economy contractors in some way or another, but I accept that it comes with the territory. Why is my total double the price of the single item I ordered? If I make a special request in app and the restaurant actually reads it and does it, I'll definitely tip. (The above rationale is exclusive to food delivery services and tipping couriers. The in restaurant dining experience in the states is one of compulsory tipping.) Yes, my experience with industry people seems to be a "paying it forward" mentality with no questions asked.
