We tend to look at what we do rather than what others do. As an example I flew into Le Touquet landing with an overcast sky cloudbase right on minima for the ILS,
I turned around and took off IFR just in time to hear a G reg homebuilt flying back VFR to the UK.
Funny you should say that, I experienced exactly the same thing several years ago. Flying to L2K the weather was crappier than expected, so in the end we asked for the ILS and shot an instrument approach in. We were closely followed by another aeroplane also from Bournemouth, who had crossed the channel at 400' to remain "vfr", despite the pilot holding an IR....And within about 15 minutes ther were several "vfr" arrivals from the UK...
Nuts if you ask me...
