some of the stores around here are better then others (as us know radley)......i've only had two real problems at stores......one was at petco where they wouldn't sell me clown loaches cuz the thought my 46 gallon was too small (they were 3 inch clown loaches) and another was at a LFS where i told a lady not to buy jack dempseys for her ten gallon, i got kicked out cuz they said i was loosing them buisness...........but i do have to say the petsmart that radley works at has a pretty knowlegable staff including radley himself.....
It is at our discretion and as long as we have a proponderance of evidence (just like court) than we can refuse a sale. The one thing I tell new people is that we can refuse sales if we know that it isn't right.
