...I Spilled Coffee on My Boss's New Phone...

So I started this new job at the coffee shop last month...and you know how everyone says they hate Mondays? Well, turns out it’s Monday mornings when customers are grumpy and the kitchen staff is rushed. So there was this one morning where things were so hectic that my brain felt like it might explode. Then a regular customer, let's call him Mr. Smith, walks in and orders his usual drink...but he also has this brand new phone sitting on the counter beside him. Now, I've been trying to get better about not spilling anything on anyone’s stuff because, you know, that would be pretty bad. But then I got distracted by a colleague's joke and before I knew it, splash! Coffee all over Mr. Smith’s new iPhone... And here’s the real kicker, I didn’t tell him I did it. Instead, I just quietly cleaned up my mess and mumbled an apology...and he just laughed it off and said something like ‘accidents happen’...but you know, I can’t shake this guilt. Should I have told him what really happened? It’s just been gnawing at me ever since...
