That is just adding value to their sale. If they' can't give you a good lesson from a certified instructor, ask for your money back. You can also take lessons at fishing shows and conclaves. Your next assignment is to go outside in a non-fishing setting and practice your casting. Practice on water, in the yard, at a park, or in a parking lot.
Pavement can be a bit hard on lines, but practice is more important than wear and tear.
Make sure you have plenty of casting room and aren't going to hook any eighteen wheelers on your fore or back casts. My son, Geoff, blew up a two weight rod on a '92 Plymouth van. Cars beat rods every time. Also, don't forget that you can practice in pantomime fashion without a rod. Actually, I wasn't as crazy as our cell phone users.
