My first and last experience. Walked in and stood at the door for couple mins. They looked at me but no greetings and acknowledgement. I asked is it walk in or appointments. They said not possible right away. I asked to book an appointment next day, they replied the same "sorry, we are busy". I politely asked any available appointment in the coming week? ...without letting me finish my statement they said "no sorry, not possible". Made me feel like they were not ready to listen. I don't know what can be the reason but was expecting little professionalism in dealing with customers.
