Arrows -simple or not?

[SummerDayWinterEvenings]

I would have thought they are universal in language - no? Supermarket near me has a one way system with huge arrows on the floor. Today a woman comes towards me, you are going the wrong way I pointed out as she came steaming towards me. I just need to get this -she says. I said the rules are clear -if you follow them they help everyone. She then launched into a rant about how she was a nurse and knew everything about the virus and pointing out I was spreading the virus as I was wearing gloves. She was shouting I'm a Nurse -you need to look the NHS website -and stop wearing gloves and spreading the virus. I asked her to move further away and a member of staff asked her to move on. Why is it so hard for people to follow arrow in a supermarket which are huge and clear.
