Hassan should know that drinks sales faster and expires easily thus they need cold temperature for preservation.books are seasonals and they don't expire,dry and safe places are recommended.
- Always arrange different sorts of beverages in front line for display purposes and the rest in refrigerator. -Drinks are on high demands so for Hassan to balance the sales he should give offer on sales of drinks e.g buy three bottles and get one book for free ,the price of three will cover the one book given for free. Display books facing both sides to attract customers,books with attractive pictures and writings will automatically attract attention.
