I had this when in Ramazan in Fethiye with Mrs Scunner a few years back. I went off for a look and the second I was alone I attracted the attention of a sales assistant who followed my every move from about 1" away. I went upstairs, even did the pedestrial equivalent of 3 times round a roundabout a few times and she didn't lose any distance. It was odd but a little funny but quickly became quite unnerving and certainly uncomfortable. Although she would quickly change to a particularly false smile if you turned and looked at her, she hadn't spoken a word, even when she came across into my personal space she hadn't offered a hos geldeniz or even a merhaba, just adopted the initial shadowing position.
I didn't buy anything. In fact, I didn't pick anything up or show any level of interest in any item at all. This would only have been seen as encouragement. That was my first ever visit to Ramazan and needless to say perhaps my last.
