I’m not sure if that really is a proper difference or simply down to me and most people I know using the wrong washing up techniques, but:
Everyone in Britain seems to own a “washing-up bowl” which sits in the sink and gets filled with the hot soapy water instead of filling the sink itself. Don’t really see any obvious advantage or disadvantage in any of those ways (but I’m a spoiled girl anyway hardly ever having to wash up manually – long live the dishwasher!), if anyone can think of one, please let me know. So right now it stays 0:0.
