A few Denny's restaurants were built without locks so they couldn't close for Christmas!

Denny's has been the punchline of a joke more than once in popular culture, but the success of the business is nothing to laugh at. The first Denny's opened up in 1953, on a small piece of property in Lakewood California. In just under 30 years, there were over 1,000 Denny's across the country!

Christmas time can be an awkward time of the year for someone who doesn't celebrate the holiday, or any other major holiday that takes place during the winter season. Almost all the stores, and only some restaurants are closed on Christmas, and Denny's became one of the restaurants to close on Christmas for the first time in 1988.

All but 6 Denny's restaurants closed down on Christmas. Why did those 6 stay open? Some of the Denny's were built without locks, and as a result, they couldn't close down on Christmas. If you think that's embarrassing, some Denny's owners couldn't close down because they lost the key to the front door!
