Nearly a year ago we hired a new member of staff to join our small (15) team. We are all based from home so that, coupled with the Covid-linked restrictions, means we haven't had a chance to meet over lunch, with or without a client until recently.
A few days ago I had the opportunity to have lunch with this person and I couldn't fail but notice that their table manners are quite poor. From talking with their mouth full (not open wide, but enough to be unpleasant), to holding their fork from the bottom of the handle with their 'fist' wrapped around it, I was quite surprised and disheartened. There is no way we could have this person join a lunch meeting with a client, especially given our client contacts are usually GMs, VPs or CXOs. However this person is fairly good at their job so I'd like to eliminate this table manners issue and have them join client meetings taking place over meals.
What is the most tactful way of bringing this up with them? I looked up relevant etiquette courses for business people but they are several hundreds of pounds and we would need to offer them to everyone so as to not single out this particular member of staff, costing the company thousands of pounds.
Any suggestions gratefully received. Thank you!
