Same thing happened to me with one of those laser levels that costs more than my drill. I spent an hour trying to get the stupid thing to stop flashing and just used a cheap bubble level from the dollar store instead. Now the fancy one lives in the bottom drawer with the dead batteries and broken tape measures.

Oh man, I do this all the time and it drives my husband nuts. Last month at our Walmart they had 12 lanes and literally 2 open, plus the self checkout area where 4 out of 8 machines were broken. I started timing it too, like how long each person took, and the average was almost 6 minutes per cart. That adds up fast when you've got a full cart and only two real cashiers moving people through. It really does feel like they're testing how long we'll put up with it before we just give up and use the scan and go app. The weird part is the store is always packed, so it's not like they're hurting for business.
