webcomic text:

Panel 1:
In many places, some people haggle for the best price before buying an item.

Panel 2:
In the US, some people pay full price, keep the item, and throw tantrums to get a refund.

Speech bubbles (all are the customer speaking, all in the 2nd panel):
“I’m not happy.”
“Looking at it made me vomit.”
“I want it free.”
“Call the manager.”
