Question:
A link to your patronage; an enabler of burdens.
Answer:
Mr. Saturn ATM
Explanation:
An ATM is the link to your patronage (your dad being your patron, and his money being your patronage). A shop in Saturn Valley refers to each item you purchase as a "burden", which is the only place in the game that does that. The ATM does not actually give you any "burdens", but it does enable you to receive them.
Surprisingly, nobody actually guessed this one. There were many submissions that were very very close, but didn't exactly fit. However the guesses "ATM" and "ATM Card" were so close (and arguably correct), that I'll go ahead and accept them anyway. Congrats! :D
