I've done it - mostly like +Jessica McCormick
when I'm making something for the first time and within reason I enjoy it in other's posts especially +Joseph Lee
who is both creative and informative.
What I do really dislike is being in a great restaurant, enjoying amazing food and the company of my dining companions and being assaulted by the flash, flash, flash of a phone/camera at the table next to me. If you're snapping that many shots you ought to be in a studio! Beyond that .... how do those folks find time actually eat the food and when they do get around to it, is it cold?
