It happened to me in Luminae on the Summit last year. I was solo and seated at a window table facing into the dining room. A couple at the table ahead of me, husband back to me, wife facing me, camera propped on tripod and action! I asked my waiter to ask the man to please move his camera so it was not facing me. To the camera guys credit, he did so without issue, he and his wife changed seats. If he had just been taking a photo or asked his waiter to take a photo, no problem, but for the camera to be facing me for my entire meal was more than I was willing to endure.
