I bounce 75% of commercial controls because generally they waste time I could spend riding, if the control has extended it's opening times or hired extra staff I will of course support it.
I don't use any commercial controls on any of my own events as it's just more things to fret over on the day, on my 200 It's any PoP from the controls which everyone seems to get on with
Problem with cafes in the UK is that they are a major social event for everyone apart from AUK riders IMO
not sure they waste time you could be riding, there will be just as much riding time on a route whether you stop or not, unless you don't eat enough and it causes you to slow down. But that doesn't seem like an improvement to me.
If riders are not stopping at a cafe it may be that it was too busy, in which case not much lost for the cafe, if most riders are not using a cafe control despite not being busy, organisers should be considering if there is something wrong with the cafe. there will always be some that don't stop, but the majority tend to. Is it the price, the food, the service, or is the control at the wrong time in a ride?
