Was too hot to walk home with my essential food shopping today so got the bus back. Now I totally understand them putting tape across to keep people away from the driver. But on today's bus some of the pairs of seats were blocked off by string. It seemed to be totally random which ones were blocked off. Couldn't see the point of it. Don't bus drivers trust passangers to not sit next to each other, or directly behind.
A more sensible idea would be block off every other row of 4.
I'm taking scissors with me next time.
