OMG, I have had those really nice post office people who think I do not look like a terrorist and let my hazmat through. I try hard to get them to refuse me without actually saying what exactly is in my package but then that really nice guy or gal gets a no on the report.
Another place I shop I am required to order 2 small fries for 2 adults when their giant fries cost about $1 more then each small and is exactly twice as big. Every time they try to get me to save my money and get the giant size. The issue is I agree with them and appreciate the fact they are trying to steer me away from spending my hard earned money.
