Checks and US banks
I spent 3 years in the US 98-00 and even at that time I rarely used cheques in the UK so was somewhat surprised when I opened a bank account in the US to receive in the post a box containing something like 10 check books each containinbg 20 checks - my initial reaction was how long would it take to use these. Then I discovered that 8every* month I needed to write checks to electricity company, gas company, cable company, refuse collection company, water company, car lease company, local phone company, long distance phone company ... so they started to go quite quickly. However, during that time the banks "invented" (n.b. US banks were constantly "inventing" new ideas that had been standard in the UK for a decade or so) the idea of automated regular payaments aka direct debits so eventually the rate of check usage did decline!
One thing to remember about US checks is that they don't have a check guarantee card which means that shops can be more selective about accepting checks (signs saying checks not accepted from out of state banks were common and I even saw ones saying checks from out of county banks not accepted) but at the same time the absence of a £50/£100 guarantee limit means checks were accepted for sums that no UK shop would have accepted.
Anyway, now back in the UK for me, like others above, checks are almost redundant - I never carry a cheque book around with me and they now seem only to get used for sending money to childrens schools for dinner money etc!
