Oh I do let him wait a while. Partially because I’m really not short on things to do. Partially because he’s happy enough when I get his request done in two days and I really don’t want to start setting higher expectations.

Unless everything is on fire and he’s about to present his shit to the division head and only now realised he missed something, which might reflect poorly on my tool and is critical enough to prompt immediate action, his messages can stew a bit.
