When is 24 hours not 24 hours?

When you try to go to ASDA or Tesco after 10:00 PM on a Saturday night…24 Hours is written in huge letters and you have to get really close to read the fine print. They only mean on weekdays.  They close at 22:00 on a Saturday and are open on Sunday from at 10:00 - 16:00.

At least the ATMs at ASDA are outside so it wasn’t a totally wasted journey.
