Was in the CoOp today...had to get hundreds and thousands for this evening's bonfire celebration... (eye roll) and as I entered the empty shop I almost slipped on the threshold...was slippy as it was raining and the threshold was a big, flat stone thing...not a step.
I went in and as I passed the girl on the till I said "That entrance is very slippy...I almost fell." with a smile and she said "Oh." in a bored way. 
Went and got my things and came back to pay...she was leaning on the counter....I again said "I think it needs seeing to...an older person could fall" and she said "Oh....right."
I went out and went into the deli over the road and could see as I queued that she never checked or anything!
Pissed me off...all she needed to do was mop it over...it was slimy I think due to wet leaves and rain...
