Hello, is that the DSS?

I went to the local Waitrose shop recently and was slightly annoyed to see the usual, importunistic, “Big Issue” vendor hovering at the entrance. “Damn,” I thought, “how am I going to avoid this pest, without suffering the slight feeling of guilt at ignoring him?” I need not have worried, however, as he was too busy talking into his mobile phone to bother with the passing public!
