A similar experiment was carried out in Maltese restaurants [76]. The objective was to assess if lavender and lemon stents impact the customer's dining experience in terms of money and length of time spent in mid-range restaurants in Malta. The experiment was conducted in three restaurants. However, their findings suggest that scents did not statistically impact the time and money spent in restaurants by consumers. [PERSON] et al. [77] presented a study conducted in Dijon, France, where groups of participants were exposed to the scent of melon (as a typically entree-related aroma in France) to the scent of pear (a typically dessert-related aroma). Both were presented at a very low and imperceptible level. They compared the impact of these scents to the experiment with no scent. The results showed that those who were exposed to the melon scent tended to choose more salads and less fatty entrees than those who were not exposed to this scent. Furthermore, those exposed to the pear aroma chose more fruit desserts than those in the no scent group [77]. Research about the impact of aromatization on customers was also carried out, for example, in the KFC fast food network in Mauritius. The campaign aimed at smelling their unique spice was realized. The restaurants delivered this aroma with food orders to companies at lunch time. The shipment contained chicken, byproduct, and biscuit. The intention was to release the aroma of fried chicken throughout the office and to evoke a taste for the food in busy research participants. According to the survey, 46.3% of participants felt excited about the aroma, 31.3% of participants felt very happy, 12.7% of participants felt nothing, and 9% felt relaxed [78; 79], which points to the positive impact of aroma on customers. The study was based mainly on surveys conducted through questionnaires submitted to 133 random respondents--customers of KFC--to find out how sensory marketing affects the consumption level of rational individuals. The study confirmed that our five senses have a tremendous impact on how consumers purchase and experience products, services, and brands, as well as contribute to a company's strategic marketing. The result was that the smell of the restaurant motivated customers to choose the KFC restaurant without planning [80]. Another experiment was realized in restaurants in Sri Lanka. For the study, [PERSON] and [PERSON] [81] chose the world-known restaurants McDonalds, KFC, and Manhattan Fish Market. Through the questionnaire, they collected data and realized a limited number of interviews to explore in-depth information. Data were collected from respondents (guests of the restaurants), as well as through several in-depth interviews. Findings supported the assumption that sensory marketing has a strong impact on customers, whereby smell was one of the strongest factors. We can find many other experiments realized by sellers and various concerns with using the power of smell and scents which had a positive impact, mostly on sales. We can also mention, for example, the world-famous company focused on selling donuts (Dunkin' Donuts), the company focused primarily on selling coffee (Starbucks), the Cinnabon bakery network, the Subway or Burger King fast-food chains, and many others (see more in [71]).
