Hello,<br/><br/>Why is "could" used in the dialogue given below?<br/><br/>A: If you like the fish, this is the best place in the town. You COULD have some sweet peas and mashed potatoes. What do you say?<br/><br/>B: I say that you can not say all of these things just from one dumb inkblot.<br/><br/>Is this showing to POSSIBILITY OR SUGGESTION? <br/><br/>Thank you
