It really makes people feel uncomfortable.
Her brother asked her about her monthly income, and she answered 2700 yuan.
He then asked her about her daily taxi expenses for work, and she said it was 50 yuan, so she was losing 300 yuan a month.
The cost is like this: taking a taxi to work in the morning costs 50 yuan, and taking a taxi home in the evening costs another 50 yuan, so the total daily taxi fare is 100 yuan, thus incurring a loss of 300 yuan.
This was originally a skit they were recording.
