MPA: Visiting my 3rd cousin, ex-husbands daughter in-law
Agent: Anything else while you're visiting?
MPA: Help friend with her small shop
Agent: Okay, do you have anything to declare?
MPA: Yes, 54 gallons of odourless oils and a Chinese to English Babbel Book
Agent: Sounds good, what days are you work at your friends shop and what is the house fee for 30, 45 and 60 mins? do the rooms have showers?
