Something else - my husband works at a local concert venue, and they have several stewards who work part-time well past retirement age.
There's this lovely lady called Audrey, who, when she first retired, put herself through drama school and now does bit parts in dramas and ads, as well as being a steward.
Hubby likes the older stewards - they are a reassuring presence to staff and clients alike and are just as effective in getting the latter do as they're asked.
