I read a paper on a study that showed that people spent more time, and therefore more money, in a restaurant with a lavender scent.

We suggest that the positive effect that the lavender scent had on the length of time spent in the restaurant was caused by its relaxing effect (Diego et al., 1998). Studies found that lavender increased drowsiness (Buchbauer et al., 1993) and induced sleep (Van Toller, 1988). Therefore lavender seemed to relax people which in return led them to stay longer in the area where this smell was diffused. Perhaps, this relaxation effect, in return, had an influence on expenditures; when relaxing, the customers ordered additional items including alcohol and/or coffee and thus increased the amount spent.
