Rest Area should give warning if Dellang Shop hasn't been visited in Chaos

Currently, in a Chaos, if you go to a Rest Area and you press Leave and you never visited the Dellang Shop, it doesn't provide any warning whatsoever. Considering that not every Rest Area has a Dellang Shop, it's easy to habitually do the typical Rest/Training > Leave, and miss the opportunity to spend. This is especially bad if it's the last Rest Area in the Chaos and you essentially built up a LOT of Credits that are basically all wasted now. In my opinion, if you haven't even tapped/clicked on the Dellang Shop and just pressed Leave, the game should warn you - similarly to how during battle the game warns you that you have unspent AP when you end your turn.
