"Will you provide a receipt?"
Though you may think this is a common expectation, it is good to ask ahead. If the answer is 'no' that's a red flag to not continue with this towing company. Explaining why could take a while so we'll just say that, if you don't have proof of a tow, did it ever happen?
"How long until you arrive?"
Though the way they answer this doesn't really give much indication about the business. If it's a high response time, they are either busy, or don't have very many operators/trucks.
If they have a low response time, they could be really slow (which happens) or have A LOT of trucks.
Either way, this is more to do with your availability. If you are in a rush then a lower response time is obviously a good thing!
Next post we'll talk about why it's important to 'vet' a towing company or to pick one that is vetted.
