My nephew is currently doing UE/DD/Instacart to make ends meet and if their experience is reflective, most of their customers deserve shitty service. I helped them write some scripts to analyze data from Gridwise (delivery+mileage tracking app) and the tips average around 3-5% of the gross. Even in California with Prop 22, that's not going to add up to a livable wage.

Don't be surprised when the permanent underclass you depend on doesn't give a shit about your moldy strawberries.
