10ish years ago I used to travel to the UK on business a fair bit and to save money did a "reverse ex-EU". I'd buy a ticket for YYC-LIN return and nest within that a separate ticket for LIN-LHR. I'd allow about 2 hours in LIN to have lunch in the lounge and head back to LHR.
I did this on a Canadian passport, and I was questioned a few times about why my ultimate destination was LHR as I'm stepping off the plane from LHR. They would ask to see my ticket, shrug, and stamp my passport.
