Worthy of a thank you?
Wait, hold the line, it seems that everyone is so h*ll bent on the shower issue they miss other AND more important things - like a staff who is clean, pleasant and knowledgeable. Or a place that is actually cleaner than a full litter box.
Maybe it is just me, but I don't care about the shower credits as much as I care about seeing employees getting free food or being taken care of before a customer.
I don't care about how shiny and sparkley my card is but care about the person behind the counter knowing what she is talking about or staying off her d*mn cell phone and paying attention to me, the person who pays their wages.
Sorry Pilot, T/A and others but I count more than your employees do, I am the one who makes it possible to turn a profit, not them. SO enforce the simplest rules, like employees getting free food or being served before paying customers or hiring and paying people who actually care.
So in other words if you want to thank me, act professional.
If you want to thank me and think it is all about the card in my wallet, then harmonize your two different systems into one card and don't expire showers, points or anything else because they are already paid for by my purchases.
