Pretty much every time I'm on the underground now and use the wide gate with my children I have an adult slip in through with me! It's so often that I now try to check behind me to make sure there is no one around but they seem so quick and appear out of nowhere! The staff don't say anything I guess they don't want to be attacked but it's very annoying and id hate for them to think I'm letting these people in and I'm with them. Does this happen to anyone else? Seems to be a bit of a free for all now
