Same experience here. Learned to order "Thai-hot" while working in Frankfurt (Germany) and frequenting a Thai food truck. Nearby was "Best Worscht in Town". Try it when in Germany - http://bestworschtintown.com They sell sausages and fries. You have to choose a flavour and the level of spiciness for the sauce/relish. Latter ranges from A to F. I can manage D (333,000 SCU according to web site). For F (short for FBI or Fking Burning Injection, 1,200,000 SCU) I heard that they require to sign an indemnification agreement.
