I REMEMBER WHAT THAT'S LIKE
let the people at the bike shop know how you feel.
See if you can go in back of the building or somewhere else where there isn't as much of an audience or as many obstacles.

I went to one bike shop where the guy was pushing the bike out the door while saying "go ride around the parking lot" and I was saying " I don't want to ride around the parking lot' (it was a busy, crowded lot)
He didn't listen and I bought my bike somewhere else.
