Why would a single homed customer not take a default route?


1: They are concerned about bandwidth — if a customer sends a packet and there is no global route, they can drop and not "waste" the transit bandwidth. This is actually useful in some specific niche cases. 

but, more likely

2: they want to feel studly.  "Real" networks are default-free. Therefore, if I want to be a real network (and feel like a real network engineer), obviously I should do the same…

hey,

Yeah, no. Provided they are singlehomed customers who generally set (or take) a default route to that transit, they are completely fine. Their transit knows the prefix and will use it. It gets more problematic for multihomed customers.

Well I have no idea why do you say that all such customers always have default route pointed to their transit provider. If that is the case then everything is OK ofc but you can't really take that for granted.
