All the time. It seems almost like that's a standard in this industry. Even my larger clients that I've known for over a year will still ask me the week of (usually 3 or 4 days before) to shoot something. Other times, I'll look at their calendar and call them asking, "Hey, I saw that you had XXXXXX (Big event) coming up... did you need for me to shoot that?" Luckily my schedule is fairly flexible and I can deal with it, but I don't like having to change or cancel the plans I've already made. With that being said, I'm shooting a swim meet for TYR the two days before I leave for a cross-country trip.
