The meaning behind ：我只是打酱油的

Hi ChinesePod team, my question is this:
Hi I would like to know the real meaning behind the sentences 我只是打酱油的.
Can please give some example as well?

Thanks

Eddie

Hi Eddie,

Literally, it means I am just someone responsible for buying soy sauce. It’s a slang on the Internet which means: it’s not my business. For example,

• A：这件事你得负责。
  [Zhè jiàn shì nǐ dé fùzé.]
  You have to take the responsibility.

• B：我就只是个打酱油的而已，你找别人吧。
  [Wǒ jiù zhǐshì ge dǎ jiàngyóu de éryǐ, nǐ zhǎo biérén ba.]
  I am just a nobody. Find someone else.
