Up for it? Already did it, last time I renewed my phone contract. Went to the shop, insisted they printed the T&C in English, not Chinese, read it standing there in the shop, amended the bits I wanted to in pen and signed. Didn't even need the thermos and sandwiches, only took half an hour.
It worked because the assistant wasn't briefed on how to handle it, and thought it was easier to complete the transaction and hand the paper on to administration.
