I'm allergic to pork!

As everyone knows, there are many kinds of allergies. Dust, ticks, food, etc. I don't have the ability to break down pork. Most other people misunderstand. And ask me questions. 'Are you on a diet?' 'I envy you. You don't gain weight.I don't explain or reveal my allergies anymore. There were times when it was hard to eat together at work. Because they feel left out when I don't share the menu. It is sometimes difficult for Korean companies to distinguish between business and private.

Is it a completely different contract job away from a 10-year job? Is it the same thing?
