Dear Sir,

Briefly, in the plaza near my practice, I have seen highly competitive businesses destroyed by putatively compentitive conduct. 

A cafe was built up, and had a great following, because of the personality of its owners, and the quality of their coffee and food. My friends having established that market for the plaza, the centre management then opened outlets opposite them, adjacent to them, and three on the floor below. No price or quality imporvement followed, but the café did go under.
