省 means “save” (as in “save money,” 省钱) or “conserve” (as in “conserve electricity,” 省电).
I feel like I’ve been seeing this particular in-store advertisement in Carrefour forever, but it’s time I pointed it out, because it’s a nice simple example of characterplay:
Carrefour keeps trying new things to deal with the shopping hoard that flows through its boundaries every day here in Shanghai. I mentioned a “basket-only line” idea a while back. I’m not sure when it disappeared, but it seems that idea is long gone. Lately I noticed another interesting idea:
The text reads:
> 如您前面有4人排队 If there are 4 customers waiting before you
> 请按键 Please press the button
> 减少您的等待时间是 Reduce your waiting time by every second in cashier line
> 我们的承诺 is our commitment
Decent idea, in theory, but the reason that button is so funny-looking is because the button is actually missing (presumably destroyed by all the constant frantic mashing it received).
