My boss has been super supportive helping me to navigate my next promotion milestone. My promotion is about to happen and I would really like to get him a gift as a thank you (i have already thanked him verbally lots and he knows I have really appreciated his help) but just want to show my gratitude. Problem is very well off and therefore I am struggling to think of a gift! I was thinking maybe a restaurant voucher for him and his wife….any ideas greatly received! Thanks
