Young sales man and his Manager

Pedro was appointed as sales person at a local store.
While on one of his shifts, a lady approached him and asked if they had ‘Peach Jam’ to which he bluntly replied, “Out of stock.”
At this, the lady immediately turned to leave the shop in disgruntlement.
It was then that the shopkeeper, who had been looking on, called Pedro aside and told him,
“When a customer asks for a product that is out of stock, you apologize for its unavailability, and then offer other types of the same product. For instance in this case it was peach jam; offer other types of jam like pineapple jam, guava, apricot jam and so on.”
Next, came in another lady who asked for toilet paper and Pedro politely replied,
“I am sorry ma’am, we do not have any toilet paper right now but you could try some Carbon Paper or Sand Paper!”
