Staff found sunglasses in parking lot&returned it

Hi guys I was down in Cape Town this weekend and booked a car with you guys for the first time at the airport branch. Once in Cape Town I realised that I forgot my sunglasses in the trolley when I took possession of the car. I tried to call you guys but gave up and thought it was too late in any case. On our way back to I took a chance and asked the lady at your booking office if they might have them. She said that they did and that one of your staff handed them in. She said she did not know who handed them in, but it would be great if you guys could find out so that I may send the gentleman a token of my appreciation. Thanks for your great service and honesty!
