Makes perfect sense.

I think seeing the tip first is a good option for the app.

I don't exactly agree with the ability to go and just change the tip afterwards. There should be some checks and balance system so people can't do that without providing some proof of reason and administrative approval for changing tips afterwards, because I bet that's a tactic shitty people use too to get good shoppers.

Maybe they will enhance things to have "preferred shoppers" where you can just text your peeps like "When are you going to be available bro?"

That would be way better, I would love to just pick my own personal shopper and pay them well for the help. Things are not easy when you don't have a car, so in all essence it's a good service for people like myself.
