Final answer:
To avoid confusion, Angelo should avoid using idioms and provide clear and specific delivery details based on the company's delivery window of 10 a.m. to 2 p.m.
Step-by-step explanation:
Angelo should remember to be specific and not use idioms or colloquial phrases when speaking with a customer, especially when those phrases can be misunderstood due to regional differences. In the context of Richard's Furniture Company, which delivers furniture from 10 a.m. to 2 p.m., a more accurate and factual statement regarding delivery time should be provided to avoid confusion. It's important to clearly communicate delivery expectations, which would involve stating exactly when, between the delivery hours, the customer should expect to receive their items, rather than relying on an ambiguous expression like 'faster than a New York minute.'
