Last week I visited Boots in Trowbridge with my granddaughter to PURCHASE an Essie nail varnish strengthener. This was not available on the shelf. However on leaving the aisle I noticed a shop assistant closely watching me. Whilst I realise shop lifting is on the increase I am NOT A shoplifter and do not appreciate being so closely scrutinised in this way. Shortly before entering this shop we had been to Boots Opticians where I purchased a new pair of prescription glasses so I am really not interested in stealing a varnish costing a few pounds. I am 73 years of age and will never visit this shop again.
