i guess it varies by location. my counter, and all the other locations in my state, do 30 min, e/l/c appts for all events. if they want foundation, they get passed off to whoever is working the counter. we explain to them when they make the appt that it is just e/l/c, so that they don't expect foundation as well (like in a regular 60 min appt). otherwise, this pushes all of our appts back, making each appt run behind.
i would call and ask what all they do for your appt, so you aren't surprised when you get there.
