Ask, Don't Assume

With technology making staying in touch readily available and accessible, and that can be great, what isn't great is when someone assumes how to contact you and/or pay you.
 
When you meet someone with whom you want to engage, ask him or her "If it is appropriate, I'll follow-through on our conversation...would you prefer a call, text or email?", and then use that preferred method.
 
Similarly, when paying for services or splitting a charge with someone, ask what form of payment works best, as there are many, so saying something similar to "Okay, so I owe you $XX, and I'll get you that by tomorrow. Do you prefer Zelle, PayPal, Venmo, or ApplePay?" is smart, as not everyone uses all forms of payment, and if not set up, have hoops to jump through to access what is rightly his or hers.
 
Asking, and not assuming, works well in life in general. Respecting preferences and noting choices makes for good rapport-building and good relationships, so in contact, payment, and other things, do ask, don't assume!
