Which is not considered a standard phrase used in customer interactions at Uniqlo?

The phrase "Thank you for your purchase!" is generally used at the end of a transaction when a customer has completed their buying process, typically during the checkout phase. While it's a polite and positive expression, it does not commonly initiate or maintain ongoing interactions with customers who are browsing or seeking assistance in the store.

In contrast, the other phrases—“Would you like a basket?”, “Thank you for waiting,” and “Hello, how can I assist you today?”—are all proactive ways to engage with customers and enhance their shopping experience from the outset. They are geared towards providing service and assistance, encouraging interaction, and acknowledging the customer's presence and needs in a more immediate context.
