Story time: My Friend called me at 3 am because his car battery was dead, and I heard about taxis charging 25 or so to jumpstart your battery (never tried it myself), so I sent him a taxi number before, and he called 3-4 times and they kept rejecting him. I seen this website and sent him the 2 numbers they listed and after 1 call to the second number, the person came within 10 minutes, was respectful and instead asked for a smaller amount to jumpstart the car. 5 stars from me and my friend!
