Because of the anesthetic, Medical offices won't release you after a colonoscopy unless someone meets you to accompany you home.
I asked for an escort from MRHS the first time I had 'the procedure.' He was very gracious about waiting hours until I came-to, farting (aka passing air) and then talking his ear off in the taxi, "Thank you; thank you; when I feel better, I'll invite you for coffee." When I asked Margaret to call him for me and repeat the invitation, he declined and asked her to tell me that he needed no thanks.
In gratitude, I became an escort for MRHS too, as soon as I retired. I'm not always happy to do it; but I know from experience how important escorting is and volunteers are always needed. Happily, volunteering (like virtue) is its own reward.
