I'm irritated by pushy sales clerks who keep pestering me while I'm trying to decide what -- or even whether -- to buy. I'm forced to deal with their agenda (to get me to spend my money) instead of being able to concentrate on mine, which is to sort through my needs and wants for a particular shopping excursion. That's why I appreciate car dealerships being closed on Sundays, remnant of our blue-law days it may be. I can comparison shop and narrow my choices down to a few, which I can then research on my own and even ask the salesman about, if I want to, later.
