Kinsey was in no rush to find someone with a grudge against him. He deliberately allowed Mertun to take him around or to the place his best friend wanted.
The aim was to reveal himself and make the one targeting him came out of their hiding place.
He was also not afraid that Mertun will get involved. Mertun was the successor of the Tettero family as well as the leader of an elite army of one of the rulers in Prussia. Mertun was the only person who can be relied on apart from the chief of the Oostven tribe.
It's just... he really hopes Mertun did not invite him to this kind of bar.
Actually, this bar was not small, in fact, you could say that it was quite large for the size of a bar. The price of beer here was also relatively high for the lower middle class. What made it look 'trash' in Kinsey's eyes are the waiters who only wear sexy and seductive bikinis and hot pants.
