As a business owner personally I’d have made the call that honouring the vouchers would generate more goodwill and lead to repeat visits, but I guess they are within their T&C’s.
I find that although the trails and location are spot on, and that I deeply admire the founders efforts (listen to interviews with them, they are sound people), the front line service is somewhat lacking. Café staff are some of the most miserable sods I’ve had the displeasure of being served by and there is a general sense of officiousness with regards to certain rules (don’t try and eat near to closing time, despite the kitchen being packed of staff they don’t want to know).
Shop guys vary, I’ve had amazing service and another visit where I might not even have existed. As always there are two sides to every experience, so this may not be representative.
Can’t fault the trails, and I guess that’s the point, but it feels to me like the day to day management suffers.
