I spent a week in Germany and Austria two decades ago. After having semi-stale Kaiser rolls for breakfast every day (at multiple locations), I refuse to eat those darn things ever again.
Those Kaiser rolls in Germany gave me the worst hemoroids... I do not know how they do it there
I spent 1/2 a summer taking a field course at a university, drank heavily each night, woke late, hungover and missed the hot food at breakfast which meant a cold crappy bagel and cream cheese every day.
Took me 10 years before I ate a bagel with cream cheese again.
