We have validation tools to find such errors. You can also make a map note. Automatic processing is not an argument as it needs to cope with such cases anyway, there is always some error somewhere.

moving it to fix me is not a good idea. You can use http://ypid.de/~osm/evaluation_tool/ tool to improve the opening hours. Errors do not need to be fixed for the sake of fixing, you should improve it or leave it.
