These days I'm doubtful.

The local charity organization I work for helps the poor and is dedicated to improving the environment by selling used articles. I'm working at local charity organization with no pay, and I'm proud of my work.
 
But these days I'm not so sure. Some volunteers only work here to find a job. This is because some companies require you to be a volunteer first.  In most cases, volunteers have no passion, and they tend to quit soon after.  Which means everyday I have to face new coworkers, and there is no chance to say goodbye. It makes me sad. 

Some clients and customers treat us poorly.  Today, a patron asked refund for swimsuits 14 days after purchasing them. Legally, purchased items can only be exchanged or refunded within a week;  underwear or swimsuits never be exchanged or refunded.  We explained about the terms and conditions of sale before she purchased the items, so she knew about it. However, she said she didn't want to lose 3,000 won. (3000 won is not that much money. We give this amount to the poor.
Refunding items means we can't give money to the poor).

She argued that her overseas trip was delayed because she had to come back for a refund.  Ha!... overseas trip... I could swear that she was rich and being unreasonable.

Of course, there are many good customers - they make us happy. But there will always be the small percentage of customers that will tarnish the purpose of volunteer work and helping the needy.
