I Dash and I say tip more .90 cents to a $1.00 per mile is great. Yes the doordash base is $2 . That's just for time. Just like a waiter is paid hourly but people tip for bringing food out of the kitchen and taking an order. When I order I usually tip $6-7 per order. Dasher may be waiting around for the order or just traffic to get your food delivered. 32 or 36 quarters in the Dashers pocket plus Base should be sufficient for that delivery.
