An ordinary request outside the offer

In a constructed pizzeria case, the offer covers food and the restaurant has made no undertaking to obtain footwear. A customer asks the waiter to buy sandals and claims that being a customer entitles them to that service. Clarifying the offer identifies the unsupported extension: the customer may ask, but this arrangement gives no footwear obligation. The waiter can decline without persuading the customer to prefer a narrower offer. Help finding a shop is optional. If both already understand this boundary, a brief answer suffices.

A separate concierge offer changes the inquiry. Read its actual scope and any undertaking made under it; neither the word customer nor the restaurant setting decides the result. If an authorized concierge promise has already created a duty, use the preceding undertaking-and-revision reasoning. The initial freedom to decline a service cannot establish release from that later duty.
