Because a guy at my gym today told me about his friend there whos a 260lbs cage fighter. Ex special forces who benches 550lbs for 8 reps without a spot! Oh and hes got a tiger tattoo on his chest! 
550lbs for 8 reps would make him one of the best benchers on the planet.

The guy at your gym was obviously chatting shit.
Never been to Physique Warehouse Gym either. The only "hardcore" UK gyms I've been to were:
Muscle FX in Croydon
Reflextions in Dartford (Terry Hollands trains here)
Metroflex in Sydenham
Muscle Works in Bethnal Green
Prefer commercial gyms to be honest.
