SPIER WINEFARM; unprofessional Picnickery staff

Spier has a wonderful and relaxing atmosphere, yet my only complaint is about some of the staff at Vadas and the Picnickery who do not seem to be well trained. My niece visited Vadas with us about a month ago. We had some queries and went to the counter. I experienced the staff in Vadas to be unfriendly and unprofessional when replying to our queries. I felt very embarrassed, since I invited my niece and her family to visit Spier with us. My husband and I visited the Picnickery numerous times and although some of the staff there are very well-mannered, helpful and able, we mostly find them to be unfriendly and seem unwilling to serve us. Sometimes you are made to feel that you are an inconvenience to them and are interrupting their conversation with their fellow staff member. It has happened on many occasions that we stand at the food counter waiting for assistance, while the ladies ignore us, carrying on with their conversation. I'm sure you that you don't want your customers and especially your regular customers to feel unwelcome?! This complaint is about the ladies inside the Picnickery and not about the coffee barista outside, as he is always very professional.
