I have a chatbot that is designed to answer questions or conduct service for customers. One of the services we have is to respond to customers that ask about "exchange rate":

[Example utterance 1] "what is the exchange rate like on this app?"
[Example utterance 2] "where did your guys exchange rates come from?"

However, there are several utterances that mention this service implicitly:

[Example utterance 3] "want’s the best value for sending money to home country"
[Example utterance 4] "what is the best time to change money"

Notably, implicit utterances do not literally mention "exchange rate". Please brain storm a scenario that the customer might mention this service implicitly and generate the actual utterance. Provide exactly two different responses that are separated with 6 asterisk symbols: ******.
