8. One dollar lawyer- The blatant coffee mix PPL scene with Nam Goong Min was funny and in line with his eccentric character. It felt like a fun fourth wall break which fit the character. Also you would expect a character in a high stress law profession like his to stereotypically drink a lot of coffee anyway while doing a mountain of paperwork or during meetings.
9. Vincenzo- I would argue that the various ppl luxury goods/brands (watches, suits, sports cars, wine etc) were fitting for the Suave archetype portrayal of the ML. As extravagant as it was those products sold the lifestyle of a suave mafia consigliere.
