Dropped the GT550 rear wheel into my dealer this morning to get the tyre changed, and he was chuckling over his daughter's latest escapade. She' working for something social - I unremember exactly what - and she's looking after a guide dog[1] right now, for reasons I didn't fully catch. Anyway, she has to take it walkies and everything, so she takes it to Sainsbury's, because guide dogs are allowed in. And, staring into the middle distance, she says: "All right, Sandy, we need washing up liquid," and sets the dog off. Of course, it's her leading the dog, but nobody knows that. And she stops it by the washing up liquid, reaches out , feels the bottles, and selects one. "Thanks, Sandy. Now we need some flour. Flour, Sandy!" And off they go again. And again. While the other customers just gawp and whisper among themselves. "I didn't know they could do that!" etc etc. Seems half the customers of Epsom Sainsbury's are now convinced that guide dogs can do the shopping. Excellent gag. [1] They cost £60k to train, apparently.
