Me too re the delivery person. If we have pizza delivered, I wash my hands then leave a tip in an envelope taped to our door saying "thank you!" hoping they have hand sanitiser in their vehicle. They deliver outside, ring the bell and step away to make sure we answer basically. One guy chose not to take the envelope and I felt so bad for him, sign of the times indeed. Another told me I had no idea how much he appreciated the thought. Not sure it's right or wrong to do that, I could overthink it .
