I'm regularly confused by tipping. I was never confused by tipping until the gig economy. There's a tip on almost all of the gig services I use now, with zero explanation of how the tip affects the gig worker. The tip should be a reflection of the workers contribution to the service. I probably won't ever tip a company. DoorDash has raised $2Bil from investors. They're using this money, presumably, to attract customers and suppliers through advertising and low pricing. DoorDash is one of many companies using VC money in this way. Now I'm supposed to subsidize the VC's subsidy of the product?
