On the way home from London today Mrs N and I dropped in on an "off motorway & major route" cafe that is reknowned for serving excellent grub at excellent prices.
We didn't pitch up until about 3pm and found that they were clearing up to shut up for the day, weekdays they never shut before 7pm.
When I queried this they were quite willing to serve us, and the service was as good as ever, but the owner made it quite clear that if he wasn't going to make money on a regular basis, there was no way he was going to keep the place open when no one was there.
The point is that this applies to all aspects of business, I admit that perhaps aviation is a bit more tricky than other industries, but if the customers don't turn up and spend their money when the best offers the owner can make are available, then don't expect the facility to be there ad infinitum.
