Yes

; I am also the vet doctor too...i've had children wait in line (or some just approach me during the line) to "repair" their animal (either they undid it or whatever)....
I politely finish the one I am making and ask the next child if they mind that I help the animal...and will make their balloon immediately next (never had one say "no" yet).
The biggest problem is that more adults and 'tweens demand the balloons (unpaid volunteer church events)...and verbally talk as if Pedals is not listening (to all) conversations... things like
1. can't you go faster
2. i've been here 45 minutes and the line hasn't moved
3. can I have three balloons (so and so are scared of clowns) {if I see the people in reference, and they are I might}
4. when I politely state that the line starts back there (pointing clownishly of course); they state to their children no honey, we don't want that
stupid balloon
With all the comments Pedals usually does not reply to them ---just continue talking and twisting with the child in front..
Makes the event go quicker and the child is usually happy in the end!
