No problem. If Sam's not competent yet, they just classify his sound as background and ignore it. Does a musician get thrown by the chink of the cash register? the squirting of the beer? The slamming of a door? No.

Oh - I forgot that 'meth' means something different across the pond. Here it's methamphetamine, a cheap and all-too common toxic street drug. Just now I saw an article where an Englishman put meth on the charcoal for a barbecue. Must be different stuff.
