Here is the sentence I don't understand. This is the dialogue between A and B.
Now A has food truck which was B's truck. B is working at Speedy Lube for living. Speedy Lube looks like a fictitious Car Maintenance & Servicing.
A came to B to ask something and then he said this sentence before leave.
A: Hey, if I bring your truck back here to Speedy Lube, you gonna cut me a deal seeing as how it used to be yours? You know, before you hit rock bottom.
I really don't get it the bold part. Could you help me?
