That can happen unless you cook it for a very short time or a very long time. Let the squid sit in the soup pot for an in-between time (and what other treatment would it get at an express-lunch joint?), and you'll have a rubbery situation on your hands. Rather than order curry fishball squid noodle soup ($6.75), I should have known well enough to ask for soup sans cephalopod, then confine my grumbling to the flat spice profile.
