Cultural conundrum

On the walk home from ShopSmart (my local grocery store) tonight, I had a rather interesting encounter. The minivan driver stopped and asked me if I "want a drop". It's rather common for Barbadians to stop and offer rides to each other, especially to pedestrians carrying packages. But he was driving a minivan, which costs BDS$1.50 per ride. Thinking he was trying to get me into his van, I politely refused, but as he drove off, I doubted myself and felt bad about (potentially) refusing his hospitality. I asked my roommate & her Bajan boyfriend, and they agreed that the phrase "want a drop" supercedes the fact that he was driving a minivan. Add in that the driver was probably the same guy who drove me to the university this morning, and yea, I passed up a free ride home from the store. It was a crazy cross-cultural conundrum for sure!
