All the bloomin time. I usually have to book a slot in the garage a couple of days in advance, which she then conveniently forgets about when it's time for me to go do some work. So after she huffs and puffs I tell her I'm going to be up there (the other end of the garden) for about 2 hours.
Every time though, guranteed, after half an hour she'll be knocking on the door asking "how much longer you going to be?"
