Redeemed fake food stamp. Which offense?

I would like to know what offense or what offense I fulfill when I create a food stamp myself, print and use.

The following facts:

A contender with the police (let's call PKA Huberle) will book online via an appropriate form for his lunch break next week. The lunch breaks take place on the grounds of the police, are spent in uniform and eaten in one of the canteens on the premises. Since PKA Huberle is still in training, lunch is subsidized and costs only 2.65 euro. On Sunday, PKA Huberle rethinks its meal plans again. His order is not changeable. Then PKA Huberle takes his laptop and created by Word own invented food stamps with non-existent name and the new food wishes. He prints these stamps and uses two of them. After using the second stamp, PKA Huberle gets a guilty conscience and entrusts himself to his trainer, who immediately reports the described facts.

For which offenses did PKA Huberle make himself punishable, did he even make himself liable for punishment and what consequences does he now have to expect?

This is called fraud and forgery, presumably the police career is over immediately…

I already discovered §267 StGB. What exactly does legal traffic mean in this case?

The act of giving a truth (the food) upon presentation of a document that entitles to receipt (the voucher).

Many thanks for the answer

Whatever the offense that satisfies, the candidate was the longest time contender. He can go pack. He does not have the necessary aptitude for police training.

For sure.
