Yes, bagging your own groceries is the standard cultural expectation in France in 2026. Unlike in the U.S., where a dedicated clerk often bags items, French cashiers primarily focus on scanning products at high speed. As the items slide down the short packing area, you are expected to bag them immediately to keep the line moving. It is also important to note that most French supermarkets, such as Carrefour or Monoprix, do not provide free plastic bags; you must bring your own reusable "sac cabas" or purchase a heavy-duty one at the register. Furthermore, at many "hypermarchés," you are required to weigh your own produce and print a price sticker at a station in the fruits and vegetables section before heading to the checkout. Forgetting to do this is a common faux pas that can result in a "gallic shrug" from the cashier and a delay for the entire line, so always observe if the produce section has scales before you reach the front.
