Who needs tech?

My bathroom scales are on the blink. Or they were. Electronic ones. I step on them and a message appears on the mini screen: "O-Ld". What? Overload? Come on, I may have been snacking too much during lockdown but that's ludicrous. Maybe it's a zero, not O. So maybe it means "zero liked". It's possible     it doesn't speak English so perhaps it's "me no like...". Me no like what? Or whom?

Have my scales been hacked? GCHQ checking I've been getting exercise?

Wait, maybe it's "Oiled". It needs oil? Off I go my local garage, which has finally opened after lockdown. I met the owner recently in Lidl; he was bemoaning having to pay rent throughout the closure, even though no income. Puts my bathroom scales problem in perspective.

Anyway I did what you always do if your computer goes weird - switch it off then back on. Only there isn't a switch, or a reset button, so I take out the batteries and re-insert them. No different. Obviously therefore it's the batteries. So I buy new ones and insert them. No different. Money wasted.

Off to Asda. Face mask on. Mechanical bathroom scales £4. Bargain. No problem. Check out lady advises me to keep the  receipt in case they are faulty. Don't bother, I'll buy another one. Although not a £4 one if that doesn't last.

Anyone need four 3 volt batteries, shaped as circular discs?
