1+ on the price tags. Buy a label maker and in 1-2 hours one employee could price the whole store!
I personally don't like to be bothered while shopping around or have employees stand close to me while I look at products.
A simple Smile and "Hello, Welcome to New Fish, feel free to look around and take your time" will suffice for me.
Also, I wanted to mention the small SPS frag tank, that is in between in the main coral tank (the long one) and the giant DT in the back of the show room. The sticks in the small sps frag tank usually don't look as awesome and healthy as the ones in the main DT, how come?
