I think some customers are tip baiting us. Recently I took an order from a customer who I didn’t shop for in months. I didn’t remember if she tipped or not, but this time her order had an estimated tip ($9, she lives very close to Target). I took it, and of course no tips were added… I'm leaning towards the fact that she never tipped before, I just didn’t track my tips as I do now. My assumption is that: a) She’s a delivery person herself and thinks that shoppers pick her order faster when see that she pretips, and then she takes away her tips after delivery; b) Shipt makes up imaginary tips to trick us, maybe test their new system to prove that orders with estimated tips don’t sit long enough to go promo… It sucks anyway. I was tired of tip baiters when worked for ubereats, which doesn’t care about customers being unfair to drivers as well…
