Reflecting on refraction

A wet day today, but I had to go downtown to post a parcel so made that my exercise for the day. I don't mind going out in the rain if I'm well waterproofed, as long as it's not windy! 
 
Not a great day for photography, so I mucked about with some reflections in Tesco's car park - they have more than their fair share of puddles! This is a comparatively new building which houses my dentist on the ground floor. I felt I had to invent a limerick specially for this picture!!
 
Limerick of the Day:
 
A young member of Oban’s Men’s Shed
Was approaching the dentist with dread!
But with so much refraction
They messed up his extraction
And they pulled out his toenails instead!
