Wild Bean Cafe at BP Ferny Grove have a great barista who makes excellent coffee, is friendly and never gets the order wrong. All the staff are friendly and it's becoming a regular coffee stop for me in the morning on my way to work.
No car wash there. But the actual shop is very good. The staff could be a little more enthusiastic about their job. Slushies are very good and are highly reccommended for the taste and low price. Reasonable fuel prices. Air and water and clean inside building toilets.
