Wait a minute... wait. Those service fees I've been opting to pay haven't been going to the shoppers/drivers who are processing my order? On my last order I asked the shopper to specifically go out of her way to check on an out of stock item. I did this with the assumption that my 7 dollar service fee was going directly to her, and that she would therefore be happy to go out of her way. When the delivery person (I think the same as the shopper) came by and I smiled at her, I thought that was a "we're square", not a "sorry for not tipping you" smile.
I'm livid. It's on instacart to pay fair wages with the delivery fees if they think it's a problem. Their misleading double fee system is unfair to both me and (more importantly) the people who are directly providing me with service. I'm sick of the uber-ish "on-demand" service culture abusing their non-employees under my dime.
edit: funny thing is, I just watched the infamous episode of Kitchen Nightmares about Amy's Baking Company. In the episode, Gordon Ramsay becomes furious when he finds out that the customers' tips aren't going to the servers. He goes into the restaurant and asks the patrons if they would have tipped if they knew this and everyone agrees no. The owner meekly explains in a follow-up episode that he does this so he can pay the waiters a "fair fee". https://en.wikipedia.org/wiki/Amy's_Baking_Company. This episode utterly destroyed Amy and her husband's company. Instacart, I love your service. It's changed the way I grocery shop and I planned on being a regular, high-value customer. Please don't make me question my decision on this.
