H-E-B review: "express" lanes

This evening 3/16/22, I stopped at the HEB on Bandera and 410 around 7 pm. The following problem occurs nearly every single time I go to the store. People who very obviously have more than 15 items, casually stroll up to the "15 items or less" express check out, and the cashiers literally never politely inform them that: "This lane is 15 items or less." Today, a new record was set as a man with a basket literally filled with dozens of bags overfilled w avocados (individually counted) rolled up to the express and the cashier said nothing. I understand that they do not wish to anger any such individuals, yet they never consider how that angers all the people inback of them whose time is now wasted.
