The owner of this shop is very good at fixing bikes, but is ridiculously possessive of his customers. Even though I was a frequent and high-spending customer, he'd complain if he noticed a part on my bike not purchased at his shop.
When he found out I was getting a discount on a headlight light from another shop, he called the distributor and had the other shop's account suspended for providing "too much discount".
I will never shop there again.
Google "Busch & Muller Aaron" if you're curious.
