Jigjag, thanks. I'm not skilled enough (on my keyboard) so couldn't put the accent in 'the du constructeur' - that's just 'builder's tea' - the stronger the better for me.
I did get two slices of toast, buttered toast, with my beans. There was also a wide-ranging set of condiments, though I've never known anyone put mayo or tartare sauce on beans on toast. I think the café just puts one of everything on their little tray.
There was a surprising lack of banter in the Copper Kettle, but that was perhaps because all the employees were speaking French. There must have been a dramatic incident at some point - the word 'Merde' cropped up many times. I do hope no-one was actually murdered.
Have a nice time - and a nice meal - on Saturday.
