Need to continue shopping upstairs at this two-story Paris grocery? Don't bother looking for an
elevator, there isn't one. Instead, load your cart onto this conveyor belt and then ride along
beside it on the escalator.
By the way, the French have solved the problem of the runaway shopping cart (that is to say,
shopping cart theft). The carts require a deposit to use. Insert the coins into the locking
mechanism attached to the cart handle and the cart is released from its stall. When you return
the cart and re-attach the locking key (on the chain) to the stall your deposit is refunded.
