Ordering food online is amazing because it's so easy. However, you might be ordering more than you need, according to Eat24.
Almost anything can be ordered online now, and restaurants are really starting to take advantage of that. A lot of food delivery services are noticing a trend, though — including Amir Eisenstein, the chief marketing officer of Eat24:
"The difference between online ordering and offline is that most restaurants tell us orders are bigger and higher. For example, if you order a pizza over the phone you'll just tell them to bring an XL pizza and a Coke. But when you go online, you see the whole menu. All of a sudden, people order appetizers, ribs, salads, and stuff they don't normally order over the phone. They have more time on the menu, they spend more time on the menu, and they order slightly more items than over the phone."
There could be other factors here, of course — maybe people having a party are more likely to order online — but the logic makes sense. When you're hungry and everything is visible, your brain goes wild looking at all the pictures of food. If you've ever grabbed too much on one plate at a buffet you get the idea. Keep that in mind the next time you plan to order some food online and order with caution.
