Dear Jessica,
Happens I use a Medicaid cab twice a week to go to an adult social program an hour away. Tip them a small tip each way, (wish I could tip them more, but I can't because I have a very low income).
Am glad I have a professional, clean and sober driver.
If they had to hang around all day, I would pay for their meal at a restaurant and to hang out at a coffee house.
That Italian couple were probably seeking the advice of a specialist, and I rejoice that they were in your care!
Yours truly,
Monica
