Helpful people living in Brussels?

Last evening I left wok a little late, went to the car and found I was going nowhere quick. I had left lights on and the battery was dead. I am not a member (yet) of Touring (AA)), it was already dark and drizzling. I tried the following. Lifted the bonnet of the car, put up the triangle 60 meters behind the car and stood behind the car with the jump leads in my hands and tried to catch the attention of the cars going by. I expected to wait for sometime.
By the eight car, I had a helper in an old Mazda who pulled over and we connected. In two minutes I was on the way home.
