Hi Bryan
Welcome, and God bless you
Warm regards, trishie
Specific to your question…
A day of grace and rest from work
2184 ‘Just as God “rested on the seventh day from all his work which he had done” (Gen 2:2) human life has a rhythm of work and rest. The institution of the Lord’s Day helps everyone enjoy adequate rest and leisure to cultivate their familial, cultural, social, and religious lives.’
2185 ‘On Sundays and other holy days of obligation, the faithful are to refrain from engaging in work or activities that hinder the worship owed to God, the joy proper to the Lord’s Day, the performance of the works of mercy, and the appropriate relaxation of mind and body. [Canon 1247] Family needs or important social service can legitimately excuse from the obligation of Sunday rest. The faithful should see to it that legitimate excuses do not lead to habits prejudicial to religion, family life, and health.’
2187 'Sanctifying Sundays and holy days requires a common effort. Every Christian should avoid making unnecessary demands on others that would hinder them from observing the Lord’s Day Traditional activities (sport, restaurants, etc) and social necessities (public services etc), require some people to work on Sundays, but everyone should still take care to set aside time for leisure. With temperance and charity the faithful will see to it that they avoid the excesses and violence sometimes associated with leisure activities. "
Although the Church also states that employers and public authorities ought to 'ensure citizens a time intended for rest and divine worship"…
2188 …if a country’s legislation or other reasons require work on a Sunday, the day should nevertheless be lived as the day of our deliverance…"
The Catechism has the Imprimi Potest of the present Pope.
And I think you can take it as read that you’re not forbidden from carrying money…or some restaurants and sports facilities might take a dim view of not being paid! [see 2187!

I hope you find some help in this reply.
