Souma is really susceptible to cracking up, and even memories will put him into laughing fits. But being self-conscious about this, he always tries to hide it. When he does this again at a clothing store his friend works at, the friend asks him why he does that, especially when it's so easy to tell anyway. Later, Shun also repeats the same sentiment...
Excuse me, do you have this in a medium?
المعذرة، هل لديك مقاساً متوسّطاً من هذا؟
Ähm, entschuldige,
habt ihr die auch noch in M?
Disculpa…
Disculpa…
Excusez-moi, vous auriez en réserve
ce gilet en taille M ?
Scusa,
Com licença, você teria
este no tamanho M?
Слушай, а есть такой поменьше?
