No E-Books Allowed in This Establishment

I’m not a coffee drinker, so this problem hasn’t occurred to me yet, although I guarantee that I’d vote with my wallet on this one. I almost never sit down to drink or eat in this manner without something to read, and these days that pretty much means reading on my iPad. I’d stop going to an establishment that said I couldn’t read while I drank or ate. I understand that some inconsiderate people hog all the space in a place, but I say target them and not the person catching up on some reading or email over a drink.
