Yap...i literally did not like the person who was physically doing the job on cat con. Rest of the staff was good. However, as far as performance of car is concern, it is not like the same as i felt few months back when i cleaned it with liquid / acid wash. There is a slight difference in performance.
Nevertheless, many ppl have shared their good experience with that particular shop. So Majority is Authority. One can go there if any success story satisfies you.
