The only issue is that non-EU citizens are required to retain the paper receipt provided at entry. While this is somewhat preferable to passport stamps that waste more space, once you have 77 of these it gets a little bulky to carry around.
What paper receipt! I am a non-EU citizen and the paper receipt never works at LHR!!! I've asked every time and they've just said to go . . .
