Answer:
Employees attitude to customers (Customer Relationship) and the quality of the food are the two most important trends that would bring about an increase in sales.
Step-by-step explanation:
The first instrument of effective sales is an establish relationship. If a customers visits a restaurant to buy food and does not feel welcomed, the tendency to return back another time is very slim. Hnece, taking the scenerio in questions,the employees do not have the right attitude for keepiing their customers loyal to their product irrespective of whether the product is good or bad.
On the other hand, the reason for visiting a restaurant is to eat good food and not bad. So, when the quality of food cooked by the restaurant does not meet the taste and quality expected by the customer, the possibility of having such customer come around again is low. This invariably implies loosing the customer and the chain of connections such customer would have brought to the restaurant.
In summary, having the right employees with good customer relationship and chefs with good food recipes and quality is likely to result in the restaurant experiencing an increase in sales
