Tell you a story....I was driving back home from work one night. Truck Tranny went out...North Tulsa. Pulled into a McDonalds...went in asked four black older guy's if they knew of a Auto Parts store near. One said he did...and he took me there..I bot some Tranny fluid and something I thought might fix it..He was a very nice guy...and did not need to help me.
Turned out...tranny was toast. Called a buddy from work...He came and got me..and I slept in the hospital that night.
So....I hate to be that way. But I'm aware of what is going on around me...and have my head on a swivel.
Be professional, be polite..but have a plan to kill everyone you meet.
Had a similar experience traveling through South Carolina with a friend. Car started giving trouble. First went to one repair shop, and the white guy said he wanted $100 to open the hood. Went down the road to a black mechanic, who did a great job fixing the problem for a very reasonable price.
The problem is, the small-but-significant probability of things going bad leaves me unwilling to take chances with my kids.
