I waited in line for around 15/20 minutes with two people in front of me, and several people behind. The staff did not seem aware / to be concerned that a large number of people were waiting. I also then had to wait whilst an 'invoice' was produced at the end of the sale. This process seemed very cumbersome. I am fairly new to photography and did not find the process of buying from you particularly comfortable. A lot of jargon was used, and little effort made initially to guide me to what I needed. Once we had got through this the sales assistant was helpful, knowledgable, and polite.
