South of Scotland Electricity Board - website on Saturday opening hours wrong!
Clydesdale Bank - website opening hours for Bridge Street Wick wrong! (think it closes at 2pm not the advertised 4pm)
Bank of Scotland - website opening hours for their Bridge street branch wrong!
Citizens Advice Thurso - open according to website - actually closed!

We are not two months into the lockdown I would have expected that most of these would have found time to update their website presence! (Certainly big enough to have dedicated IT staff!)

Please feel free to add others

Wickers World seems to be up to date (small enough to care AND big enough to cope)
