True ; but he is drunk. I doubt he can remember the driver's face though
If he can get on board a taxi on his own, he is not that drunk and if someone else put him on the taxi, that person should be able to to see at least the gender, estimate age or maybe the race.
Else ask Comfort to send message to all their drivers to mail the CF cards back to Tammy. Then case close. Ask them not to poke into returning the camera. I mean sending CF cards by mail will be easy or just drop into the letter box.
