An English man a Scotsman and a Chinaman

An English man a Scotsman and a Chinaman get a job on a construction site.
The manager comes by and says “ok English guy you’re in charge of bricking, Scotsman you’re in charge of sweeping and Chinaman you’re in charge of supplies”. So the manager leaves and comes back 2 hours later, the English man and Scotsman are sitting on the ground twiddling their thumbs and the Chinaman is nowhere to be seen.
The manager says “what the hell are you lot playing at, i’m not paying you lot to sit around and where’s that Chinaman?” , the men reply, “well he’s in charge of supplies and we never got any bricks or a broom to do our jobs, he just ran off somewhere”
So all 3 of them go off in search for the Chinaman, they eventually pass a large pile of rubble and suddenly the Chinaman jumps out from behind with his arms in the air and yells “SUPPLIES!”
