1. Размер: маленький, средний, большой — adjective agreement

The barista asks Masha:

Маленький, средний, большой?

These three adjectives describe the size of the coffee cup (стакан — masculine). They agree with the noun in gender, number, and case. Here they are in the nominative masculine form.

Masha replies: Я буду большой.

“I’ll have a large one.” — the noun (кофе/стакан) is omitted because it is understood from context. This is very common in café and restaurant Russian: you name the adjective without repeating the noun.

Я буду + adjective/noun is the standard way to order food and drink in Russian. Literally “I will be [having].” It is warmer and more natural than просто дайте мне (just give me):

Я буду большой раф. — I’ll have a large raf.
Я буду борщ и котлету. — I’ll have borsch and a cutlet.

2. Сделайте с собой — imperatives and “to go”

Masha asks for her coffee to go:

Сделайте, пожалуйста, с собой.

“Please make it to go.”

The construction с собой (literally “with oneself”) is the standard Russian phrase for “to go / takeaway.” It is used in all cafés and coffee shops.

Сделайте is the polite imperative (вы form) of сделать — “make / do.” In service situations, the вы imperative is the norm.

Infinitive Polite imperative (вы) English
сделать сде́лайте make / do (please)
подождать подожди́те please wait
попробовать попро́буйте please try
приложить приложите  please tap (your card)
С собой vs. здесь: When ordering in a Russian café, the barista or waiter may ask: С собой или здесь? — To go or to stay? These are the two standard options, just like “for here or to go” in English.

3. Оплата картой или наличными — instrumental case for means

The barista asks:

Оплата картой или наличными?

“Payment by card or cash?”

Both картой and наличными are in the instrumental case. In Russian, the means or instrument by which something is done takes the instrumental case.

Nominative Instrumental Meaning
ка́рта ка́ртой by card
нали́чные нали́чными in cash
ру́чка ру́чкой with a pen
ло́жка ло́жкой with a spoon

Masha pays cash: Маша оплатила наличными.

French parallel: In French you pay par carte / en espèces. In Russian: картой / наличными. The instrumental case in Russian functions like the French prepositions par and en — both express the means of doing something.

4. Оплата не прошла — impersonal constructions with не

When the card payment fails:

Извините, оплата не прошла.

“Sorry, the payment didn’t go through.”

And after the second attempt:

Ничего не получается.

“Nothing works / it’s not working.”

Не прошла — past tense of пройти (to pass / to go through). Used for payments, transactions, and processes that either succeed or fail.

Не получается — impersonal: “it doesn’t work out / it’s not happening.” The subject is nobody — it simply isn’t working.

У меня не получается. — I can’t manage it. / It’s not working for me.

Не получается is one of the most useful impersonal phrases in Russian — for anything that isn’t going as planned: technology, cooking, learning a language. It expresses failure without assigning blame to anyone.
