I often have coffee out and am not worried by china cups, they have to go through a dishwasher. However, I think that allowing possibly unwashed cups to be handled as part of normal food service goes against food handling regulations. I trained in food chemistry and worked in environmental health (in a role now known as a licensed food safety officer), carrying out inspections in restaurants and care homes.
Also, like some of you, the thought of wooden platters being used for food goes against the grain (literally). I don't really see the difference in risk between staff serving food either in reused cups or on wooden platters, neither of which may pass through a dishwasher. So perhaps I'm not on my own after all.
I am concerned about the risks to paying customers who have a right to expect suitable hygiene standards. Just because the risks to me are higher than average, it doesn't mean that I am paranoid. Well-trained staff are the key to keeping paying customers safe, I'd like a barista like Deedaa to serve me though.
