I blindly tip 20% at restaurants irrespective if I sit down, buy take out, or have something delivered with one exception: if I buy take out, but I am just buying drinks that I took out from the fridge, then I don't tip at all.

My hope is that there will be sufficient political and societal will to expect employers to pay their employees a comfortable wage, and for everyone irrespective of whether or not they are an employer, employee, or self-employed to pay 100% of the taxes they owe without resorting to de jure or de facto loopholes or having an unreasonably high tax burden.
