What can this mean? If you can go out and buy Scotch Tape, certainly somebody, somewhere, took that tape and scotched it. Therefore somebody:
Blocked my tape with a wedge or chock in order to stop it from rolling away, but if so I didn't receive this wedge or chock with my purchase and therefore want my money back;
Made a small cut, groove or incision in my tape, which serves no purpose. I want my money back.
Put an abrupt end or halt to my tape, which is inconvenient, because I needed that last bit;
Injured the tape so as to render it harmless, as in the pinioning of troublesome geese. This I approve of.
Soaked my tape in Scotch, which explains the flavour.
