I haven't been asked my real name in ages!
I have never rebooked a no show. There might be certain circumstances that I would, like they had lots of great feedback and offered what sounds like a legit excuse, but they would only get 1 second chance. I've never had that situation yet though.
I had one guy no show on me when I booked the hotel specifically for his booking, so when he text later with excuses I told him there would be a ?40 charge (I never expected to see it, but if he wanted to book again that was the deal). He has rung and text numerous times for months since trying to book, not once offering the cancellation fee, just acted like it never even happened.
