> "how on earth is that viable" Visit a London park on a hot day and the queue for ice cream vans is amazing. Even though people could probably walk for <5 minutes and get something from a shop cheaper. > "you're charging WHAT?!" Yeah, last time I looked at one (couple of weeks ago), it was getting on for a 50% premium over the local corner shop (<5 minutes from the van!) which is already a 50% premium over a supermarket.
