Do others have good examples of waitstaff giving you a lecture or being arrogant?

I was just at a 2 star Michelin restaurant in London. Great food and great service, except:

the first incident was when a server came over mid-course and told me I was using the wrong piece of cutlery for the course I was on and suggested I should change. hmm - it was working OK for me!

then I spilled a tiny drop of sauce onto the tablecloth in front of my plate - maybe the size of a pencil eraser. A server came over with a napkin and made a huge show of placing it over the spot. No discretion, and I felt like I was put on display.
