Why NOT to Play the English 1.c4?! Opening

It's nothing rated or serious but I got the better of someone extremely easily earlier at club night with the black pieces playing against his 1.c4?! which no-one has beaten me with it otb... yet

The checkmate is a pure classic

He missed it lol, I saw it moves ago that's why I had to set it up! Although I give 1.c4?! an inaccuracy I'm only joking around it's just I don't like the opening, and I always refute it. Simples!
