For over a year we've had a reservation for a reception hall and block of 10 rooms in a local hotel. We're doing an event for 100 people, mostly local but with several out-of-town guests. Some time around 3 months ago management changed. The "new lady" sold off our rooms and was argumentative when asked to fix it. Like is so often the case with incidents like this, the problem-causer is never available on the phone so we just dropped by the venue one night to try and catch her there. No luck on that, but there we found our saving grace. A young girl working the front desk, who'd been out of town for a couple of weeks, had gotten back to work and found the total mess created by the "new lady." She listened patiently to everything we had to say, was very understanding and immediately began taking steps to making things right. In talking with the desk girl, the problem-causer was actually the owner. I mentioned she appeared completely unsurprised by what we were saying. She wasn't, as the owner had created an identical problem just a couple months prior! It's clear the desk girl played no small part in getting things straightened out for us - in effect doing both her job and the job of a proper manager. We'd like to reward her for ascending her given role and helping us. What would be an appropriate gesture in this instance?
