I agree with the comments about scooters, they can be quite dangerous and not suitable for shops. They should be left at home when going shopping. There's also a motorised rider (I don't know what it's called) which is even more dangerous and older kids use those. The other thing which I remember from when my kids were young and still see and hate, is Mums who shout and swear at kids who are crying and threaten them with a smack.
