...because I'm seeing more and more parents who just don't bother to make any effort at all to pick anything off the highchair or floor. Moreover they don't seem at all embarrassed at the sight of all sorts of food and general mess left behind.
A table will never be immaculate after my family has dined at it, but I would always, say, clear up a high chair tray with a napkin, so the staff can clean easily after we've gone. Plus I wouldn't leave masses of food on the floor either, if that's where it's, ahem, ended up. Not saying I get out the Dettox floor wipes or anything, just think it's right to show willing. What do you all do ?
