"That's too bad," says the bartender, "Maybe I can help you with your problem." "What problem?" asks the elephant. The elephant in the story is demonstrating a deficiency in

short-term memory

Explanation:

The elephant is demonstrating a deficiency in short-term memory. This is because the elephant completely forgot about the current conversation that he was having with the bartender just a couple of seconds ago. Meaning that he is forgetting things happening in a short-time period after it happening. This occurs when the individual has short-term memory problems. That is why the elephant asks "What Problem?" since he forgot the entire conversation.
