Text: During both intervention periods , draught beer and cider were served in straight - sided pint and half - pint glasses for two weeks . If customers asked about the change of glassware , bar staff were instructed to follow a standardised script in an attempt to blind drinkers to the study hypothesis : " We are taking part in a research study for eight weeks , the details of which will be revealed after study completion so as not to affect the results " . The research team provided the straight - sided glassware and bar owners / managers were given the option to keep it for use after the study . During both control periods , draught beer and cider were served in the venue 's usual pint and half - pint glasses for two weeks . Bar managers received a telephone reminder at least 24 h before each new period and the research team helped with the glassware exchange if needed . If necessary ( e.g. , due to space limitations ) , external storage was arranged for the glassware not currently in use ( i.e. , usual glassware during the intervention periods or straight - sided glassware during the control periods ) . At the end of the study , the bar manager sent the research team all relevant till data for the eight - week study period , as well as a list of all special events . As soon as all data were received , the bar was transferred £ 500 to compensate for their time taking part in the study .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
