*2.3. Data Collection*

On-site investigations were made at the supermarkets in their FV departments. The work in the FV departments was conducted independently of this study, in the sense that the work was performed before the study started and continued after the study ended. Before the main study commenced, an exploratory series of semi-structured interviews and participating observations with employees at one supermarket was executed. Based on the gleanings, an interview guide and a protocol for participating observations were developed.
