I'm using WashPay. Been great so far in my self-service bays. Swipe your credit card then press the red STOP button to end your charges. We have a $12.00 safety "shutoff" in case a customer drives off forgetting to press STOP. Here's my question. I find myself being way too "nice" as a businessman. We of course need to be ethical, nice, treat others w/ the Golden Rule in effect at all times, etc. but whenever I find a bay or dog wash tub still on w/ the customer having forgotten to press STOP; I've been going through the time-consuming process of reviewing the security video, timing their actual time that they used had they pressed STOP then calling Mercury to credit their sale. This is a pain-in-the-butt process robbing my day of time. My signage is well-worded and IMO noticeable regarding how to use the new credit card system. I got to thinking... yesterday when a couple who used both dog wash tubs failed to press STOP but I noticed it when I went in to clean it and then immediately pressed it for them, I stopped the tubs at $8.32 and $10.41 respectively. Upon video review, had they pressed the STOP button, their charges would have only been $6.00 & $6.00. I was about to adjust their account for them but realized that if I did, they would never "learn" how to properly use the tubs so I've decided to just let the charges stand and if they complain, then I will educate them and happily credit their cards. I want to be 100% ethical in my business practices but are we called to "babysit" our customers in such a way if they do not call us and I build into my day a check of all my $12.00 charges then review whether these were unintended or not? It's a waste of my time and I doubt if you guys would run your business this way. Your comments? Thanks. - Carl
