My bays have 2 floor mat holders each. I want to install 2 more holders, giving the customers the option to wash their 4 floor mats. I am confused whether to install all the 4 mat holders in a straight line on the same wall or install 2 on each wall. My rationale for installing 2 on each side is that it will disrupt the "flow" of the customer as he/she has to now walk from one side of the bay to the other. As all we are selling is time, it might help add up. Or am I just thinking too much into it and should just install all on the same wall and be done with it.
