What restrictions are in place between the countries you were travelling within?Too many of you trying to be too clever.
The point is not whether it is a 'common travel area'. There is a pandemic on and there are rules between the different countries. These include mandatory negative tests and quarantine otherwise you will get refused entry.
The fact you can willy nilly get away without having to follow any procedures is not really very good.
