Hotel breakfast, hard boiled eggs, milk in jugs.
Why are boiled eggs not bishul akum? Shulchan Melachim?
Other interesting topics are raw fish (some can be identified reliably by color, etc), utensils (glass v metal, cold v hot, 24h & Davar Charif), & bread (pig lard being primary concern for those who eat Pas Akum AFAIK).
