You could put an "if" loop in the script that starts
service B. Something like, if service A is running
then start service B, else wait a while and check
again.
I recommend limiting the number of loop iterations.
Set it up so that, say, the third time service A is
found not running, the program terminates and displays
the message that service A hasn't started. If it isn't
starting properly you want some kind of notice so you
can go see what's wrong, rather than have the script
that's supposed to start service B just hang forever.
