Today is the day when we should point our fingers toward the sky, right? No? But… look at the picture! The thumb on that hand is… pointing up!
Of course, this sign was meant to refer to points (noun) that can be earned by shopping at this mall, not pointing (verb) up. You can get more points than usual if you shop there on Wednesdays. If it were twice as many points as usual, then it would be “Double Points Day”, but I was told that it’s not quite that big of an increase. So I guess the best English would be:
“Down” is not a place, so it’s strange to use it with “to”. Just like you can’t “go to shopping”, you can’t “go to down”. Often, “down” is an adverb, as in “this escalator is going down.” It can also be an adjective, as in “the down escalator.” You could use it either way to correct this sign:
O These escalators only go down
O Down escalators only
