Yesterday, I was enjoying dinner and drinks with my team members and company management of my work division. Both I and the rest of the team had been drinking (2-3 drinks) during the evening event. I am the team manager. Some background:
My team member no longer drinks due to previous AA history
Towards the end of the event and within earshot of all others at the event, he asked me if I can drive him home. We live within half hour from each other in the same town
Unfortunately this town where we live lacks public transportation so I could not have asked my team member to take public transport home.
No discussion took place on who will be the sober designated driver before this event.
He saw me park my car , so he knew I drove in today. For obvious reasons, I will not be driving home.
I gave him a lift to the event. I made an assumption that he believed I wouldn't be able to drive him home.
Questions
As I am my team member's manager, how could I either avoid answering such uncomfortable question or best answer him when other colleagues are present who also will not be driving home?
Did I do the right thing by suggesting my team member take a ride share service home? If so, do I have a duty to cover his incurred expenses of this ride?
Any suggestions on how a designated driver system should work?
Edit Normally, I would not have a second thought to a team mate asking me for a ride home , but I found the question strange in the circumstances we faced. I felt it strange when he was expecting yes, and yet knew I and other colleagues had all had drinks.
