Oh yeah, sorry my bad. It should be a "No".
As to your question about the article to use in the word "bakery", yes you are correct that everyone of us knows what a bakery is but that is a dictionary definition (general). However, on your post you are referring to a specific bakery where you bought your bread and where you saw the three persons mentioned. We don't know which bakery it was.
Moreover, there is no anaphoric reference for the word bakery to justify the use of the article THE. Maybe, it is worthy of mentioning too that if a noun is first introduced or mentioned be it in spoken or written form, the correct article to use is the indefinite articles (A and An).
To further elaborate this, please refer to the examples below:
A. Can you pass me A chair. (unspecific, any chair)
B. Can you pass me the chair. (specific, the listener knows it. The chair could be just in front of them.)
For the noun bread, bread is an uncountable noun. The denomination as used in your examples - 3 pesos, 5 pesos, has nothing to do with the number of the word BREAD. Maybe you are coming from the idea that we can buy a piece of bread for three pesos. It's the same with the erroneous statement " One rice" whenever we order a cup of rice in restaurants and "two soaps" whenever we buy two bars of soap in stores.
The notion of countability/uncountability and singularity/plurality of nouns becomes a challenge for us, second-language learners, because some nouns are used in our country incorrectly and only few people have the courage to point out the errors and correct them. This is what is making the learning of the English language a bit complicated as teachers would need to challenge the schema (stock knowledge) of their learners. What was incorrectly learned in the yesteryears would need to be unlearned - that is if there is such a thing as unlearning.
Remember, we have to use the language the way it is used by the native speakers for us to effectively communicate our thoughts to our listeners/readers..
Whenever seized by doubt, you may consult a dictionary or sir Joe. ☺
