OP - If you don’t want to eat / drink inside, then don’t, but to avoid a drive thru coffee in fear of the cup being “contaminated”, IMO that’s just too much.
A good summary.
Coffee isn't "safe" and never has been. Back in January my friend asked me to hold her cup of black coffee a moment so she didn't tip it on her toddler's head. As I took it, the disposable cup squidged and spilled onto my hand. Fuck it hurt! Within 2 seconds I dropped it to the floor and bolted to the toilets to rinse under a running tap for the next 10 minutes. Even so it still throbbed when I got home and needed more soaking in cold water.
Mind you, a virus would not have stayed in good condition on that cup 
Take-away has been sufficiently low risk as to stay open all the way through. Some chains closed temporarily due to lack of demand and to work out working practices, but it was legally avaliable to consumers throughout.
While not nil, the chance of catching the virus from a surface such as a cup is incredibly low.
Sitting in your car to drink it, or indeed outside, incredibly low.
Going indoors, the risk increases. The busier it is and the poorer the ventilation the more the risk goes up.
I have mainly sat outside this summer, but occasionally sat indoors where it was very quiet.
Hearning about people staying indoors 99.9% of the time for the past 6 months and probably going on to a year is incredibly sad and a very unhealthy way to live. Going outside is the best way to get vitamin D which is reputed to be a good defence against the virus as well as it's other benefits. It's important for mental health to get outdoors, connect with seasonal change and to move. It's much much harder to be active if permanently in a restricted indoor space.
