Could you help me?

Hi, there

could you help me? Please!

1) Let us say you are in/at(in or at) a starbucks and you are buying a coffee and a muffin, and you say to the cashier after she/he tells you the price: "Did you get the coffee too?" "Did you include the coffee too?" "Did you get the coffee in/on there too?"

All of those are correct. :)


2) do you say "FROM a brand?"

"My phone is an Apple" or "My phone is from Apple"
"My shirt is (a) Ralph Lauren" "My shirt is from Ralph Lauren
"I bought that cookie from that brand you like"
"I bought a computer from another brand. It isn't from apple."

This question is a little complex.

Saying something "is" is only used for the brand. It can't accidentally be confused with something else.

Buying something "from" tends to imply a physical store or person you bought the item from. Often this is okay for talking about brands because many stores with a brand name only sell their brand. However, this isn't always the case. 

For example, you could say, "My phone is an Apple from Verizon."

What would you say?

Please

Thank you!

I would say "is the coffee included?" or "Did you include the coffee"?

2) do you say "FROM a brand?"

"My phone is an Apple" or "My phone is from Apple" My phone is an Apple.
"My shirt is (a) Ralph Lauren" "My shirt is from Ralph Lauren My shirt is from Ralph Lauren
"I bought that cookie from that brand you like" Correct
"I bought a computer from another brand. It isn't from apple." I bought another brand of computer. It isn't an Apple.

What would you say?

Please

Thank you!
