I think they do appreciate the effort, esp from the british – I got a tenner off some ski gloves once because I asked for them in crap French
Word of “warning” on sounding like you speak the lingo:
Went to Bordeaux quite a few yrs ago with my Mrs (on a car tour). Fancied a vineyard tour so got a list from the tourist office and phoned around. Was a Sunday, so got lots of knock-backs and much practice in my opening gambit on the phone. Got through to one bloke who started back with the rapid-fire French and I couldn’t catch hardly any so he was shouting down the line, thinking I couldn’t hear him. Eventually he heard me telling the wife that I couldn’t work out what he was saying … “Oh, what – you’re English ?!”
Was a Swiss geezer who’d learnt to make wine in Australia. He spent ages showing us the place (he was pretty new there & ded enthusiastic). Told him from the off that we wouldn’t be able to buy much from him (only an MX5 fully loaded already) but he didn’t seem to mind and did us proud. Still feel guilty now that we only took half a dozen bottles (only got 13 in all told before the car was rammed)
