You're poor if you look at the price of groceries before putting them in your trolley.
You're poor if you'll drive to a different petrol station because it's cheaper.
You're poor if you stop in to save money.
You're poor if you sell things rather than donate them.
You're poor if you check your bank balance before buying anything less than a house.
You're poor if you wash your clothes rather than buying new ones.
You're poor if you ever use public transport (1st class air travel is just about acceptable).
