A new estate agent opened up around the corner from us. There's a ledge at the bottom of the shop front windows, and smokers seemed to like sitting there on their smoko break (it's in a big apartment building with a Woolies, BigW etc). Anyway, the business owners are of Oriental background so English is possibly not their first language. They stuck a sign on their ledge saying:
"please do not seat in front of the display"
It really bugged me, and I was so tempted to scribble out the 'seat' and put 'sit'...but someone beat me to it! It only took a couple of weeks and the sign was replaced with the correct wording. Phew! What a long winded message
