Can I say this in English?
1. A mentally disturbed man burned pet filled with oil in metro and threw it on floor. While subway driver and staff were embarrassed at situation, the fire rapidly spread to entire subway and some of the station.
=> Is this sentence OK? For me, the word "embarrassed" seems an awkward choice. Subway drivers and staffs were shocked, thus this word "embarrassed" should be replaced?? If yes, what should I replace it with?
2. In the past when these fastfoods weren’t in Korea, many Koreans consumed salt only from soup and kimchi, so it was OK. But recently fastfood restaurants came to Korea, and to attract customers more and more, they add salt a lot in their food.
=> The expression "came to Korea" is OK? If not, what could be a better alternative?
Thank you so much in advance!!
