Went to Mind, Body & Flow for a colon therapy. The therapist was running behind schedule because her previous client was having difficulty during the session. Before I could get bent out of shape regarding the wait, the manager offered me a complimentary 30 min sauna while I waited. I got to relax and unwind in the sauna for free and ended up having a good colon hydrotherapy session. That's what good customer service is all about.
