I always ask “I presume you only have what’s on display but in case I’m wrong, do you have any other stuff”? (Mostly when I’m buying new shoes or a shirt, that’s pretty hard to find in my size). If they say they don’t, they don’t. Why would they lie to me, their purpose in the shop is to sell stuff.
