Sorry Mom, I Couldn't Hold it In

FARIS (8 years old) was taken by MAMA (38 years old) to walk around the modern market. After looking at clothes, FARIS had to defecate. MAMA took FARIS to a public toilet. A TOILET OFFICER was seen sitting with a scary face, in front of him was a box with a sign that said "Pee 2000, Defecate 3000, Bath 5000". MAMA brought 3000 rupiah for FARIS. While MAMA waited in front of the toilet, while stopping by a headscarf shop. FARIS went into one of the stalls, to defecate and pee. FARIS realized, he should have paid 3000 + 2000 = 5000, while he only had 3000. FARIS tried to stay calm. FARIS wanted to go out of the toilet to look for MAMA, but was immediately greeted by the TOILET OFFICER's fierce stare, FARIS changed his mind, then went back into the stall. FARIS heard the TOILET OFFICER shout and threaten someone for running away without paying the toilet fee. FARIS was scared and thought of lying. FARIS practices lying, saying he just had a bowel movement. Will Faris's efforts succeed?
